In one sentence, describe what the following article is about: By relying on mathematical calculations, your graph does not need to be as neatly drawn. You do not need to determine any measurement scale. Just sketch a ray in the general direction of your vector. Label your sketched vector with its magnitude and the angle that it makes from the horizontal.  For example, consider a rocket that's being fired upwards at a 60-degree angle, at a velocity of 1,500 meters (5,000 ft) per second. You would sketch a ray that points diagonally upward. Label its length “1500 m/s” and label its base angle “60°.” The diagram shown above indicates a force vector of 5 Newtons at an angle of 37 degrees from the horizontal. Sketch a horizontal ray beginning at the base of your original vector, pointing in the same direction (left or right) as the original. This represents the horizontal component of the original vector. Sketch a vertical ray that connects the head of your horizontal vector to the head of your original angled vector. This represents the vertical component of the original vector. A vector's horizontal and vertical components represent a theoretical, mathematical way of breaking a force into 2 parts. Imagine the child's toy Etch-a-Sketch, with the separate "Vertical" and "Horizontal" drawing knobs. If you drew a line using only the "Vertical" knob and then followed with a line using only the "Horizontal" knob, you would end at the same spot as if you had turned both knobs together at exactly the same speeds. This illustrates how a horizontal and vertical force can act simultaneously on an object. Because the components of a vector create a right triangle, you can use trigonometric calculations to get precise measurements of the components. Use the equation:  sin⁡θ=verticalhypotenuse{\displaystyle \sin \theta ={\frac {\text{vertical}}{\text{hypotenuse}}}} For the missile example, you can calculate the vertical component by substituting the values that you know, and then simplifying, as follows:  sin⁡θ=verticalhypotenuse{\displaystyle \sin \theta ={\frac {\text{vertical}}{\text{hypotenuse}}}} sin⁡(60)=vertical1500{\displaystyle \sin(60)={\frac {\text{vertical}}{1500}}} 1500sin⁡(60)=vertical{\displaystyle 1500\sin(60)={\text{vertical}}} 1500∗0.866=vertical{\displaystyle 1500*0.866={\text{vertical}}} 1,299{\displaystyle 1,299}   Label your result with the appropriate units. In this case, the vertical component represents an upward speed of 1,299 meters (4,000 ft) per second. The diagram above shows an alternate example, calculating the components of a force of 5 Newtons at a 37 degree angle. Using the sine function, the vertical force is calculated to be 3 Newtons. In the same way that you use sine to calculate the vertical component, you can use cosine to find the magnitude of the horizontal component. Use the equation:  cos⁡θ=horizontalhypotenuse{\displaystyle \cos \theta ={\frac {\text{horizontal}}{\text{hypotenuse}}}} Use the details from the missile example to find its horizontal component as follows:  cos⁡θ=horizontalhypotenuse{\displaystyle \cos \theta ={\frac {\text{horizontal}}{\text{hypotenuse}}}} cos⁡(60)=horizontal1500{\displaystyle \cos(60)={\frac {\text{horizontal}}{1500}}} 1500cos⁡(60)=horizontal{\displaystyle 1500\cos(60)={\text{horizontal}}} 1500∗0.5=horizontal{\displaystyle 1500*0.5={\text{horizontal}}} 750{\displaystyle 750}   Label your result with the appropriate units. In this case, the horizontal component represents a forward (or left, right, backward) speed of 750 meters (2,000 ft) per second. The diagram above shows an alternate example, calculating the components of a force of 5 Newtons at a 37 degree angle. Using the cosine function, the horizontal force is calculated to be 4 Newtons.
Summary: Construct a rough sketch of the original vector. Sketch and label the component vectors. Use the sine function to calculate the vertical component. Use the cosine function to calculate the horizontal component.

Problem: Article: Having good nutrition is vital to keeping your body healthy and keeping bedsores at bay. When you are healthy, your body can help heal bedsores more quickly and keep new ones from developing. If you are deficient in certain vitamins, especially iron, zinc, vitamin A and vitamin C, you may put yourself at higher risk for developing bedsores. Take vitamin supplements in addition to eating foods rich in vitamins. Eating or drinking lots of protein will also help keep your body healthy. If you're worried you aren't getting enough protein through your diet, a supplement drink like Ensure can help. Drink plenty of water every day. Men should aim to consume about 13 8-ounce cups of fluids and women should aim to consume about 9 8-ounce cups of fluids per day. This does not mean you need to drink only water. Many foods have high water content, and healthy foods can have up to 20% of your daily intake of fluids. Eat foods that also have high water content, such as watermelon, to increase your water intake.  You can also get added hydration by sucking on ice cubes throughout the day in addition to drinking water. Do not drink alcohol, as this can contribute to dehydrating your body. If you are underweight, you have less padding to protect certain parts of your body that are prone to developing bedsores. Your skin can break down more easily. Being overweight can similarly cause problems, as it may be difficult for you to reposition your body to relieve pressure. Smoking contributes to drying out your skin and is generally considered an unhealthy habit. As well, it reduces blood circulation, a condition which can contribute to increased risk of bedsores.
Summary:
Eat plenty of vitamin-rich foods. Keep your body hydrated. Maintain a healthy weight. Do not smoke.
