cos(x)=0.83

cos (x) = 0.83

x = 0.59168 \dots + 2 πn, x = 2 π - 0.59168 \dots + 2 πn

Degrees

x = 33.90126 \dots^{\circ} + 36 0^{\circ} n, x = 326.09873 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = 0.83

Apply trig inverse properties

cos (x) = 0.83

General solutions for

cos (x) = 0.83

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

x = arccos (0.83) + 2 πn, x = 2 π - arccos (0.83) + 2 πn

x = arccos (0.83) + 2 πn, x = 2 π - arccos (0.83) + 2 πn

Show solutions in decimal form

x = 0.59168 \dots + 2 πn, x = 2 π - 0.59168 \dots + 2 πn

sin (x + \frac{π}{4}) = \frac{1}{2}, 0 \leq x \leq 2 π

cos (2 x) + 7 cos (x) + 4 = 0

2 sec (θ) - 2 = 0

8 cos (2 θ) = 24 cos (θ) - 16

x, y = sin (x^{2})
