cos(x)-2=0

cos (x) - 2 = 0

No Solution for x \in R

Solution steps

cos (x) - 2 = 0

Move

2

to the right side

cos (x) - 2 = 0

Add

2

to both sides

cos (x) - 2 + 2 = 0 + 2

Simplify

cos (x) = 2

cos (x) = 2

- 1 \leq cos (x) \leq 1

No Solution for x \in R

tan^{2} (x) + 3 = 3 sec (x)

3 cot^{2} (x) - 4 cot (x) + 3 = 0

cot (θ) + tan (θ) = 2

3 cos^{2} (θ) - 1 = 0

sin (3 x - \frac{π}{6}) = - cos (3 x - \frac{π}{6})
