cos(θ)=0.3

cos (θ) = 0.3

θ = 1.26610 \dots + 2 πn, θ = 2 π - 1.26610 \dots + 2 πn

Solution steps

cos (θ) = 0.3

Apply trig inverse properties

θ = arccos (0.3) + 2 πn, θ = 2 π - arccos (0.3) + 2 πn

Show solutions in decimal form

θ = 1.26610 \dots + 2 πn, θ = 2 π - 1.26610 \dots + 2 πn

sin^{5} (x) = 4 sin (x)

tan (x) = 2 + 3

sin (a) = \frac{11}{61}

4 sin (2 θ) = 2

tan (x) = 1.3
