How do I solve: 2 sin (2x) - 2 sin x + 2√3 cos x - √3 = 0

or , where is an integer.

There are three such angles between and : , , and .

Step-by-step explanation:

By the double angle identity of sines:

.

Rewrite the original equation with this identity:

.

Note, that and share the common factor . On the other hand, and share the common factor . Combine these terms pairwise using the two common factors:

.

Note the new common factor . Therefore:

.

This equation holds as long as either or is zero. Let be an integer. Accordingly:

Any that fits into at least one of these patterns will satisfy the equation. These pattern can be further combined:
