cos(θ)=-24/25

cos (θ) = - \frac{24}{25}

θ = 2.85779 \dots + 2 πn, θ = - 2.85779 \dots + 2 πn

Degrees

θ = 163.73979 \dots^{\circ} + 36 0^{\circ} n, θ = - 163.73979 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (θ) = - \frac{24}{25}

Apply trig inverse properties

cos (θ) = - \frac{24}{25}

General solutions for

cos (θ) = - \frac{24}{25}

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

θ = arccos (- \frac{24}{25}) + 2 πn, θ = - arccos (- \frac{24}{25}) + 2 πn

θ = arccos (- \frac{24}{25}) + 2 πn, θ = - arccos (- \frac{24}{25}) + 2 πn

Show solutions in decimal form

θ = 2.85779 \dots + 2 πn, θ = - 2.85779 \dots + 2 πn

sin (x - 3 0^{\circ}) = cos (2 x)

sin (x) = sec (x)

m, f = e^{n x} cos (m x)

4 sin^{4} (x) - 8 sin^{2} (x) + 3 = 0

sin (x - \frac{π}{3}) = 0.4
