cot(x)sec(x)+cot(x)=0

cot (x) sec (x) + cot (x) = 0

No Solution for x \in R

Solution steps

cot (x) sec (x) + cot (x) = 0

Factor

cot (x) sec (x) + cot (x) : cot (x) (sec (x) + 1)

cot (x) (sec (x) + 1) = 0

Solving each part separately

cot (x) = 0 or sec (x) + 1 = 0

cot (x) = 0 : x = \frac{π}{2} + πn

sec (x) + 1 = 0 : x = π + 2 πn

Combine all the solutions

x = \frac{π}{2} + πn, x = π + 2 πn

Since the equation is undefined for:

\frac{π}{2} + πn, π + 2 πn

No Solution for x \in R

sin (2 x) = \frac{- 3}{2}

cos (2 θ) - cos (θ) = 0

cot (x) + 3 = 0

4 sin^{2} (θ) + 4 = 5

sec^{2} (x) - 6 tan (x) = - 4
