cos(x)=0.587

cos (x) = 0.587

x = 0.94344 \dots + 2 πn, x = 2 π - 0.94344 \dots + 2 πn

Solution steps

cos (x) = 0.587

Apply trig inverse properties

x = arccos (0.587) + 2 πn, x = 2 π - arccos (0.587) + 2 πn

Show solutions in decimal form

x = 0.94344 \dots + 2 πn, x = 2 π - 0.94344 \dots + 2 πn

\frac{sec ( x ) + csc ( x )}{1 + tan ( x )} = sin (x)

sec (x) - \frac{sin ( x )}{cos ( x )} = cos (x)

- 10 sin^{2} (t) = 0

x, e^{y} cos (2 x) + y = 1

cos (θ) = 0.4, sec (θ)
