1. In this Unit, Unit Q, we learned how to verify a trig function. This actually means that we must prove that both sides are equal to each other because we know our answer already. So we must use our identities, which we all memorized to make the left side equal to the right side. WE NEVER TOUCH THE RIGHT SIDE. We are just verifying that is proven to be right.
2. There are many tips and tricks that I have found helpful in this unit to help me understand it way more. One huge tip that I learned that if you can, change EVERYTHING into sine and cosine. By doing this it will make our lives easier because they will either cancel out or be equal to one. Another tip is to always work on the complicated side first that has a lot going on. By doing this first we are able to make it easier and get the hard side out of the way. A third tip is if you can, look for the greatest common factor. This will allow us to make our problems simplier and closer to our answer. The biggest tip I can give is to ALWAYS identify what you did in each step and make it neat. This will help you see where you went wrong if you did not get the answer right. It will also look nicer as well.
3. The first step in my thought process is to see which identies I have in my problem. I always look to see if I have sine and cosine together, secant and tangent together, or cosecants and cotangents together because they pair up well with their idenities. Next I look for to see if anything cancel or if I have a greatest common factor so I can simplify it even more. If none of that works, the next step I do is look for a common denominator. Once I have done one or all of those steps, usually the identies work out the way I want it to and give me the same answer as the right side. Concepts 1 and 5 are tricky, but if you practice it will all make sense. Just memorize the identities.
