cos(v)=-0.995

cos (v) = - 0.995

v = 3.04155 \dots + 2 πn, v = - 3.04155 \dots + 2 πn

Degrees

v = 174.26803 \dots^{\circ} + 36 0^{\circ} n, v = - 174.26803 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (v) = - 0.995

Apply trig inverse properties

cos (v) = - 0.995

General solutions for

cos (v) = - 0.995

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

v = arccos (- 0.995) + 2 πn, v = - arccos (- 0.995) + 2 πn

v = arccos (- 0.995) + 2 πn, v = - arccos (- 0.995) + 2 πn

Show solutions in decimal form

v = 3.04155 \dots + 2 πn, v = - 3.04155 \dots + 2 πn

5 sin (X) - 2 = 2 sin (X)

cos^{2} (2 x) + 3 sin (2 x) = 3

- 2 cos^{2} (θ) - 4 sin (θ) + 2 = - 5 sin (θ)

t, x = cos (t) + cos (2 t)

x, sin (x) = - 1
