Question

How many solutions for cos(x)=square root 3/2 for (-infinity, infinity)

Answer 1

infinite

Answer 2

Since \(2^2 - \sqrt{3}^2 = 1^2\) we see:

Answer 3

@wio the question is about how many solution for cos x. Is there any reason to approach the problem on this way? Please, explain me

Answer 4

This tells us that \[
180^{\circ } = x+ \frac x2+90^{\circ}
\]This will give us a particular solution.
