cos(x)=0.95

cos (x) = 0.95

x = 0.31756 \dots + 2 πn, x = 2 π - 0.31756 \dots + 2 πn

Solution steps

cos (x) = 0.95

Apply trig inverse properties

x = arccos (0.95) + 2 πn, x = 2 π - arccos (0.95) + 2 πn

Show solutions in decimal form

x = 0.31756 \dots + 2 πn, x = 2 π - 0.31756 \dots + 2 πn

2 cos (2 θ) + 2 cos (θ) + 2 = 3 cos (θ)

1 + csc (x) = cot^{2} (x)

cos (\frac{1}{4 θ}) = \frac{- 2}{2}

cos (x) tan (x) - 2 cos^{2} (x) = - 1

3 cot (\frac{1}{4} x) = 1
