cos(θ)=(25)/(sqrt(714))

cos (θ) = \frac{25}{714}

θ = 0.36083 \dots + 2 πn, θ = 2 π - 0.36083 \dots + 2 πn

Solution steps

cos (θ) = \frac{25}{714}

Simplify

\frac{25}{714} : \frac{25 714}{714}

Apply trig inverse properties

θ = arccos (\frac{25 714}{714}) + 2 πn, θ = 2 π - arccos (\frac{25 714}{714}) + 2 πn

Show solutions in decimal form

θ = 0.36083 \dots + 2 πn, θ = 2 π - 0.36083 \dots + 2 πn

cot^{2} (a) = 1

3 sec^{2} (x) - 4 = 0, 0 \leq x < 2 π

2 sec (θ) + 4 = 0

sin (x) = \frac{( 60 \cdot sin ( 15 5 ^{\circ} ) )}{97.72}

(1 - 2 cos (x)) (1 + sin (x)) = 0
