Which shows all the exact solutions of sin^2 x + 3cos x - 1 = 2?

x = 2k is the solution of this equation.

Step-by-step explanation:

This question is related to trigonometric equations.

The given equation is,

We have to find the solutions of this equation.

Put

+ 3cosx - 1 = 2

= 0

For this equation only cosx = 1 is possible solution.

Cosx = 1 happens when x is a multiple of 2

So x = 2k is the solution of this equation.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

according to egenuity the answer is
