Problem: Article: Inscribed shapes come up fairly often on standardized tests like the GMAT and GRE, so it is important to know what they are.  A square inscribed in a circle is a square that is drawn inside of the circle, so that all four vertices (corners) lie on the edge of the circle. The distance from the center of an inscribed square to each of its corners is equal to the radius of the circle.  To find the length of s, we must first imagine cutting the square in half diagonally to form two right triangles.  Each of these triangles will have equal sides a and b and hypotenuse c, which we know is equal to two times the radius of the circle, or 2r. The Pythagorean Theorem states that for any right triangle with sides a and b and hypotenuse c, a2 + b2 = c2.   Since sides a and b are equal (remember, we are still dealing with a square!) and we know that c = 2r, we can write out the equation and simplify the equation to find the side length as follows:   a2 + a2 = (2r)2, now simplify the expressions:  2a2 = 4r2, now divide both sides by 2:  a2 = 2r2, now take the square root of each side:  a = √(2r2) = √2r.  Our side length s for the inscribed square = √2r. In this case, the perimeter of the square P = 4√2r.  The perimeter of any square inscribed in a circle with radius r is defined as P = 5.657r! Consider a square inscribed in a circle with radius 10.  That means that the diagonal of this square = 2(10), or 20.  Using the Pythagorean Theorem, we know that 2a2 = 202, so 2a2 = 400.  Now divide both sides in half to find that a2 = 200.  Then take the square root of each side to find that a = 14.142.  Multiply this by 4, and you will find the perimeter of your square: P = 56.57. Notice that you could have found the same thing by simply multiplying the radius, 10, by 5.657.  10 * 5.567 = 56.57, but that might be hard to remember on a test, so it's better to memorize the process we used to get there.
Summary: Understand what an inscribed square is. Recognize the relationship between the radius of the circle, and the side length of the square. Use the Pythagorean Theorem to find the side length of the square. Multiply the side length of the square by four to find the perimeter. Solve an example equation.

Problem: Article: Do you want them to hug a guy they like? Say hello to that cute older boy? You can write almost anything. Also, think of a time in the future (two or three hours gives the victim to most suspense to find out who they have to talk to.) Just make sure the time isn't too far in the future. Everyone has a limit as to how long they can wait. Most people will appreciate you asking them if you can zap them, but you don't have to if you don't want to. Write what time it has to be before they can look at the zap (or find out who's on it) without having to do what it says. For example: 2:00 For example: Hug For example: Bob in Social Studies (you could also write the last name, instead of what class they share with the victim.)
Summary: Find someone to "zap". Think out what you want to zap them to do. Approach the victim. Write zap in all capitals on the back of your victim's hand. Write what they have to do. Write down who they have to do it to on the palm of their hand. If you get zapped, don't look at the palm of your hand before the designated time or let people tell you who's on your hand unless you think doing what's on your hand isn't that bad.

Problem: Article: In order to enable cloud printing for your printer, you'll need to use a non-Chromebook computer.  You can connect your printer by attaching the printer's USB cable to your computer. Skip this part if you already connected your printer to your Chromebook via Wi-Fi. Click or double-click the Chrome app icon, which resembles a red, yellow, green, and blue sphere. It's in the top-right corner of the window. A drop-down menu will appear. This option is at the bottom of the drop-down menu. Doing so opens the Settings page. You'll find this at the very bottom of the Settings page. It's in the "Printing" section of options near the bottom of the page. You'll find this option at the bottom of the menu. Log into your Google Account if prompted before proceeding. Click the printer you want to use to open its menu. It's at the bottom of the menu. Doing so adds the printer to your Google Account's list of Cloud Print-enabled printers; you can now use this printer to print from Google Chrome on your Chromebook if you're signed into the same Google Account there.
Summary: Connect your printer to a Windows or Mac computer. Open  Google Chrome. Click ⋮. Click Settings. Scroll down and click Advanced ▼. Scroll down and click Google Cloud Print. Click Manage Cloud Print devices. Select your printer. Click Add printer.

Problem: Article: Every time you (or someone with you) has a seizure it is important to write down what happened. Often a doctor will request the patient to keep a seizure log prior to any examination. Always include the date and time of any seizure, as well as how long it lasted, what it looked like, and anything that could have triggered it (such as lack of sleep, stress, or injury).  If you are the one who experienced the seizure, ask for input from people who witnessed it. When you or someone you love experiences an unexplained symptoms, it is important for them to visit a doctor. Bring along as much information as possible to help give the doctor a clear picture of the seizure activity. Prepare for a doctor’s appointment by:  Finding out about any pre-appointment restrictions, and following these restrictions. (The doctor may ask the patient to alter your diet or sleep pattern.) Recording any recent life changes or sources of stress. Writing down any medications the patient is taking, including vitamins. Making arrangements for a family member or friend along to the appointment. Writing down any questions for the doctor. In order to determine the cause of the seizure, the doctor will listen carefully to all of the symptoms and do a basic physical examination. Additionally, the doctor will evaluate the patient for physical and neurological conditions that can lead to seizure activity. The  evaluation is likely to include:  Blood tests - These will be used to check for signs of infections, genetic conditions, or other health conditions that could be associated with a risk of seizure. A neurological exam - This can help the doctor diagnose the condition and possibly determine the type of epilepsy present. This can include tests of behavior, motor abilities, and mental function. Based on the symptoms present, any previous medical history, the results of any blood tests, and any findings from the neurological exam, the doctor may order a series of tests. Tests used to detect brain abnormalities can include:  Electroencephalogram (EEG) High-density EEG Computerized tomography (CT) scan Magnetic resonance imaging (MRI) Functional MRI (fMRI) Positron emission tomography (PET) Single-photon emission computerized tomography (SPECT) Neuropsychological tests Complete Blood Count (CBC) test to eliminate infection, anemia, glucose fluctuations, or thrombocytopenia Blood Urea Nitrogen (BUN) or creatine test to exclude electrolyte disturbances, hypoglycemia, or uremia Drug and alcohol screening Determining the location of the electrical discharges in the brain can help the doctor understand the cause of  certain seizures. Neurological analysis techniques are often done in conjunction with other neurological tests, such as MRIs and EEGs. Some neurological analysis techniques include:   Statistical parametric mapping (SPM) Curry analysis Magnetoencephalography (MEG)
Summary:
Maintain a detailed seizure log. Schedule an appointment with your doctor. Request a medical evaluation. Request more advanced tests to detect brain abnormalities. Work with a doctor to pinpoint where seizures originate in the brain.
