Solve −4sin^2(x) − 3cos(x) = −3

The smallest non-negative radian solution is:

The next smallest non-negative radian solution is:

Thank you!

Step-by-step explanation:

The given expression is

We know that

So,

Let's call , so

Where , and . Using the quadratic formula, we have

Where

But,

So,

and

Therefore, the smallest radian solution is 3.14, approximately. And the next smallest radian solution is 1.32, approximately.
