Solve trig equation on interval

WebApr 14, 2015 · To solve a trig equation, transform it to a few basic trig equations. Solving trig equations finally results in solving basic trig equations. Reminder: 4 basic trig equations are: sin x = a; cos x = a; tan x = a; cot x = a. f(x) = sin 2x + sin x = 2sin xcos x + sin x = 0. f(x) = sin x(2cos x + 1 ) = 0. Next, use the trig unit circle and trig ... WebAs the cosine is periodic, there are many values of $\theta$ which have the same $\cos(\theta)$. So they are just asking for all the values between $-\pi/2$ and $\pi/2$ that solve the equation. Your solution got one of them, $\cos(0.605)$ does equal $5/\sqrt(37)$. But so does $\cos(-.605)$ You were supposed to find that one, too.
