2sec^2(x)=0

2 sec^{2} (x) = 0

No Solution for x \in R

Solution steps

2 sec^{2} (x) = 0

Divide both sides by

2

2 sec^{2} (x) = 0

Divide both sides by

2

2 sec^{2} (x) = 0

Divide both sides by

2

\frac{2 sec ^{2} ( x )}{2} = \frac{0}{2}

Simplify

sec^{2} (x) = 0

sec^{2} (x) = 0

Apply rule

x^{n} = 0 \Rightarrow x = 0

sec (x) = 0

sec (x) \leq - 1 or sec (x) \geq 1

No Solution for x \in R

2 cos (3 θ) = - 1

1 + sin (2 x) = 0

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

sin^{2} (x) = 2 - cos (x)

cos (2 x) = \frac{2}{2}, 0 \leq x \leq 2 π
