Homework Statement
I feel like I this problem shouldn't be that hard, but I can't figure out how to evaluate this equation
cosx - cosx*sinx = 1/3
Homework Equations
I don't know what to use for this, none of the trig identities seem to help
The Attempt at a Solution
I tried substituting ## sqrt(1-cos^2x )## for sinx , but I just ended up with something way more complicated. I know this shouldn't be this hard because I'm not even in a trig class, I am taking statics. It wouldn't make sense for them to give me a problem that requires more time with the trig than with the statics.
Thank You
