2cos^2(w)+cos(w)-3=0

2 cos^{2} (w) + cos (w) - 3 = 0

w = 2 πn

Solution steps

2 cos^{2} (w) + cos (w) - 3 = 0

Solve by substitution

cos (w) = 1, cos (w) = - \frac{3}{2}

cos (w) = 1 : w = 2 πn

cos (w) = - \frac{3}{2} :

No Solution

Combine all the solutions

w = 2 πn

csc (2 x) = \frac{3}{2}

sin (\frac{θ}{4}) = \frac{1}{2}

4 e^{c o s (x)} = 3

- 2 sin (B) - 6 = sin (B) - 3

sin (x) (2 sin (x) + 1) = 2
