cos(x)=0.15

cos (x) = 0.15

x = 1.42022 \dots + 2 πn, x = 2 π - 1.42022 \dots + 2 πn

Degrees

x = 81.37307 \dots^{\circ} + 36 0^{\circ} n, x = 278.62692 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = 0.15

Apply trig inverse properties

cos (x) = 0.15

General solutions for

cos (x) = 0.15

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

x = arccos (0.15) + 2 πn, x = 2 π - arccos (0.15) + 2 πn

x = arccos (0.15) + 2 πn, x = 2 π - arccos (0.15) + 2 πn

Show solutions in decimal form

x = 1.42022 \dots + 2 πn, x = 2 π - 1.42022 \dots + 2 πn

cos (5 0^{\circ})

sin (2 x) = cos (x)

arccos (\frac{3}{2})

cot (θ) + 1 = 0

2 sin^{2} (θ) - sin (θ) - 1 = 0
