I'm having trouble with this problem: https://www.screencast.com/t/I5Ng2QaqX2Bv
Any help is appreciated! :) <3
If f(x ) = sec x , tan (x) = 1 and x is in Quadrant I what is the value of (f * f)(x) ??
If tan (x) = 1, then x = pi/4
And
(f * f) (x) = f(x) * f(x)
So
(f * f) (pi/ 4) = f(pi/4) * f(pi/4) = sec(pi/4) * sec(pi/4) = √2 * √ 2 = 2
