Ok guys, please bare with me as this is my first post on here. I'm stuck on this problem. I'm not sure how to proceed to solving it. I'm in a Trig class but I'm sure this touches base on Algebra but it's been too long since I've taken it. Can't quite remember the steps. Guess I'm a bit too old and my memory isn't what it used to be. Thanks for the help.
cos ? = x / x+1
So far I used the Pythagoran Identity: sin² ? + cos² ? = 1
From there I got the alternative: sin² ? = 1 - cos² ?
Following steps are:
1). sin² ? = 1 - (x / x+1)²
2). sin² ? = 1 - x² / x²+2x+1
From there I'm stuck. Can't quite remember what that next step should be :?: . Please help. Also, let me know if I'm even on the right track. Any further clarification on anything stated please feel free to ask. I did my best to make this as clear as possible. Thanks!!
