cos(x)=0.45

cos (x) = 0.45

x = 1.10403 \dots + 2 πn, x = 2 π - 1.10403 \dots + 2 πn

Solution steps

cos (x) = 0.45

Apply trig inverse properties

x = arccos (0.45) + 2 πn, x = 2 π - arccos (0.45) + 2 πn

Show solutions in decimal form

x = 1.10403 \dots + 2 πn, x = 2 π - 1.10403 \dots + 2 πn

cos (x) = 0.78

cos (x) = 0.12

0 = cos (3 θ)

6 sin (θ) + 6 = 0

cosh (z) = - 2
