3cos(x)-sin^2(x)+3=0

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

x = π + 2 πn

Solution steps

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

Rewrite using trig identities

2 + cos^{2} (x) + 3 cos (x) = 0

Solve by substitution

cos (x) = - 1, cos (x) = - 2

cos (x) = - 1 : x = π + 2 πn

cos (x) = - 2 :

No Solution

Combine all the solutions

x = π + 2 πn

x, cos (x) = \frac{1}{4}

cos^{2} (t) = 0

sin (x) = \frac{18}{12}

csc (θ) = 5

cot^{2} (x) = tan (\frac{x}{2})
