sec(x)=-2,0<= x<= 2pi

sec (x) = - 2, 0 \leq x \leq 2 π

x = \frac{2 π}{3}, x = \frac{4 π}{3}

Solution steps

sec (x) = - 2, 0 \leq x \leq 2 π

General solutions for

sec (x) = - 2

x = \frac{2 π}{3} + 2 πn, x = \frac{4 π}{3} + 2 πn

Solutions for the range

0 \leq x \leq 2 π

x = \frac{2 π}{3}, x = \frac{4 π}{3}

2 tan^{2} (x) = 2

2 cos (t) = 1

cos (x) = \frac{2}{13}

cos (θ) = sec (θ)

4.45 tan^{2} (θ) - 23 tan (θ) + 16.15 = 0
