Problem: Article: Kids can naturally be impatient, which in turn can make you impatient, and the cycle continues. Teaching them about self-control and delayed gratification is a good way to instill the value of patience.  Removing temptation is a good way to work on patience. Hiding away anything tempting means that the kids aren’t as impatient because they can’t see what they want. Keeping things out of sight definitely works to keep them out of mind. Use a positive distraction to keep their impatience from brewing. Try singing a song, or offering them a slinky to play with, to keep their minds occupied and to practice waiting patiently. Keep calm even if your child is throwing a tantrum. This will help to make your expectations clear and consistent, which will reduce the number of patience-testing situations in the future. Rules and boundaries help to give children stability and structure which they can rely on.  Having rules and boundaries is as much about containing the kids into what is safe and appropriate for the situation, as it is giving them something to work towards and live up to. Although practicing and working on patience will make a big difference, you are still human and will make mistakes from time to time. You might slip up, but apologizing to the kids and recommitting to being patient makes the situation much more valuable. Apologizing will let the kids know that you understand that you didn’t handle the situation as well as you could have and that you will try and improve next time. This sets a good example of being able to apologize when you are wrong for them, which will help them to learn how to do it too.
Summary: Help the child to learn about self-control and delayed gratification. Set rules and boundaries. Apologize when you need to.

INPUT ARTICLE: Article: You can’t just have a pond and attract dragonflies. You need water plants in the pond to help attract them. Dragonflies love tall plants! The dragonflies will lay their eggs in the plants, and the larvae will live in them until they are grown. Then, they will use the tall plants to perch on.  Stock the pond with both submerged and floating plants. They will use the underwater plants when they are larvae, and perch on the tall plants when they are adults. Try getting eelgrass, fanwort, hornwort, anacharis, wild celery, corkscrew rush, blue flag iris, parrot’s feather, pondweed, water lilies, and lotus flowers. You can find water plants at garden centers and online. Place shrubs around the edge of the pond to give the dragonflies more places to land. This also makes your pond even more beautiful and appealing. The dragonflies will have more places to perch and live. You can plant border plants and shrubs.  For example, you can try lobelia, seedbox, or button bush. You can also let the natural grass and brush around the pond grow to give the dragonflies more vegetation. Rocks in and around your pond will make it even more beautiful. Dragonflies also love to perch on warm rocks, especially flat rocks. Place rocks in your pond and around the edges to give the dragonflies plenty of places to land. You can try a mixture of light and dark rocks. The dragonflies may be attracted to one over the other. Dragonflies like sunshine, so they will be more attracted to a pond that is out in the open with full sunshine in the middle of the day than one covered by the shade of tree branches. While you are waiting for your plants to grow tall enough for dragonflies to perch on, place sticks in your pond. This gives the dragonflies somewhere to land. You can try sticks that you get from nearby trees or bamboo stakes for plants and vegetables.

SUMMARY: Add water plants to your pond. Surround the pond with shrubs. Spread rocks around your pond. Make sure the pond gets plenty of sun. Place sticks in the middle of your pond.

In one sentence, describe what the following article is about: To find the missing angle of a triangle using the cosine rule, you need to know the length of all three sides of the triangle. For example, you might have triangle RST. Side SR is 8 cm long. Side ST is 10 cm long. Side RT is 12 cm long. What is the measurement of angle S? The formula is c2=a2+b2−2abcos⁡C{\displaystyle c^{2}=a^{2}+b^{2}-2ab\cos {C}}. In this formula, cos⁡C{\displaystyle \cos {C}} equals the cosine of the angle you are trying to find. The variable c{\displaystyle c} equals the side opposite the missing angle. The variables a{\displaystyle a} and b{\displaystyle b} are the lengths of the other two sides. Plug these values into the formula. For example, since side RT is opposite the missing angle, angle S, side RT will equal c{\displaystyle c} in the formula. The other two side lengths will be a{\displaystyle a} and b{\displaystyle b}. It doesn’t matter which side is which variable. So, your formula should look like this: 122=82+102−2(8)(10)cos⁡C{\displaystyle 12^{2}=8^{2}+10^{2}-2(8)(10)\cos {C}}. You are multiplying 2ab{\displaystyle 2ab} times the cosine of the missing angle, which you don’t know yet. So, the variable should remain. For example, 122=82+102−160cos⁡C{\displaystyle 12^{2}=8^{2}+10^{2}-160\cos {C}}. Remember that to square a number, you multiply the number by itself. For example, 144=82+102−160cos⁡C{\displaystyle 144=8^{2}+10^{2}-160\cos {C}} Make sure you square each number first, and then add them together. For example:144=64+100−160cos⁡C{\displaystyle 144=64+100-160\cos {C}}144=164−160cos⁡C{\displaystyle 144=164-160\cos {C}} To do this, subtract the sum of a2{\displaystyle a^{2}} and b2{\displaystyle b^{2}} from both sides of the equation. Then, divide each side of the equation by the coefficient of the missing angle’s cosine. For example, to isolate the cosine of the missing angle, subtract 164 from both sides of the equation, then divide each side by -160:144−164=164−164−160cos⁡C{\displaystyle 144-164=164-164-160\cos {C}}−20=−160cos⁡C{\displaystyle -20=-160\cos {C}}−20−160=−160cos⁡C−160{\displaystyle {\frac {-20}{-160}}={\frac {-160\cos {C}}{-160}}}0.125=cos⁡C{\displaystyle 0.125=\cos {C}} This will give you the measurement of the missing angle. On a calculator, the inverse cosine key is denoted by COS−1{\displaystyle COS^{-1}}. For example, the inverse cosine of .0125 is 82.8192. So, the missing angle, angle S, is 82.8192 degrees.
Summary:
