I'd like to thank Chris for the help on my last post. I just have two more problems I could use assistance on and I'll be all set.
Find the values of all trigonometric functions of theta if tan (theta) = the square root of 7/3 and sec(theta) = 4/3 (Just the 7 is the square root)
Let x=3sin(theta), -pi/2<x<pi/2. Simplify the expression: x/square foot of 9 + x squared. (whole bottom is under square root.) I have put 3sin(theta) in for the x and the x squared, is this the right step? I just cannot get the hang of this! Thanks in advance for the help!
