cos(x)=0.41

cos (x) = 0.41

x = 1.14834 \dots + 2 πn, x = 2 π - 1.14834 \dots + 2 πn

Solution steps

cos (x) = 0.41

Apply trig inverse properties

x = arccos (0.41) + 2 πn, x = 2 π - arccos (0.41) + 2 πn

Show solutions in decimal form

x = 1.14834 \dots + 2 πn, x = 2 π - 1.14834 \dots + 2 πn

cos (x) = 0.42

cos (x) = 0.36

cos (\frac{π}{3} + x) + cos (\frac{π}{3} - x) = \frac{1}{2}

cos (x) = 0.87

sin (2 θ) csc (θ) = 1
