cos(x)=-0.58

cos (x) = - 0.58

x = 2.18952 \dots + 2 πn, x = - 2.18952 \dots + 2 πn

Degrees

x = 125.45054 \dots^{\circ} + 36 0^{\circ} n, x = - 125.45054 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = - 0.58

Apply trig inverse properties

cos (x) = - 0.58

General solutions for

cos (x) = - 0.58

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

x = arccos (- 0.58) + 2 πn, x = - arccos (- 0.58) + 2 πn

x = arccos (- 0.58) + 2 πn, x = - arccos (- 0.58) + 2 πn

Show solutions in decimal form

x = 2.18952 \dots + 2 πn, x = - 2.18952 \dots + 2 πn

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

sin (2 x) = \frac{21}{25}

cot^{2} (x) cos (x) = cot^{2} (x)

4 sin^{2} (θ) - 8 cos (θ) + 1 = 0, 0 \leq θ < 2 π

4 sin (A) + 3 = 2 sin (A) + 4
