Homework Statement
Simplify and Solve the Following Trigonometric Equation
Homework Equations
[tex]\cos^2 x - 3\cos x - 2\sin x +2 =0 [/tex]
The Attempt at a Solution
I've changed the expression, but it doesn't seem any better...
I've got [tex]\frac{\cot x \cdot (\cos (x) -3)}{2}=1 - \csc x[/tex]
But that doesn't seem to help me at all...Stuck badly.
