cos(θ)=-7/8 ,csc(θ)

cos (θ) = - \frac{7}{8}, csc (θ)

No Solution for θ \in R

Solution steps

cos (θ) = - \frac{7}{8}, csc (θ)

Apply trig inverse properties

cos (θ) = - \frac{7}{8}

General solutions for

cos (θ) = - \frac{7}{8}

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

θ = arccos (- \frac{7}{8}) + 2 πn, θ = - arccos (- \frac{7}{8}) + 2 πn

θ = arccos (- \frac{7}{8}) + 2 πn, θ = - arccos (- \frac{7}{8}) + 2 πn

Solutions for the range

csc (θ)

No Solution for θ \in R

1 + 2 sin (x) - cos^{2} (x) = 0

tan (θ) = - 3, sin (θ) < 0

x, sec (x) + 2 = 0

cos (2 x) = 0.92

cos (4 x) + 1 = 3 sin (2 x), - \frac{π}{2} \leq x \leq \frac{π}{2}
