cos(x)=0.68

cos (x) = 0.68

x = 0.82303 \dots + 2 πn, x = 2 π - 0.82303 \dots + 2 πn

Degrees

x = 47.15635 \dots^{\circ} + 36 0^{\circ} n, x = 312.84364 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = 0.68

Apply trig inverse properties

cos (x) = 0.68

General solutions for

cos (x) = 0.68

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

x = arccos (0.68) + 2 πn, x = 2 π - arccos (0.68) + 2 πn

x = arccos (0.68) + 2 πn, x = 2 π - arccos (0.68) + 2 πn

Show solutions in decimal form

x = 0.82303 \dots + 2 πn, x = 2 π - 0.82303 \dots + 2 πn

cos (x) = 0.65

- 2 sin (\frac{x}{2}) - 1 = - 2 cos (\frac{x}{2}) - 1

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

tan (θ) = 30.48 (80)

cos (x) = a, \frac{3 π}{2} \leq x \leq 2 π
