solvefor y=cos(x),x

solve for

y = cos (x), x

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

Solution steps

y = cos (x)

Switch sides

cos (x) = y

Apply trig inverse properties

cos (x) = y

General solutions for

cos (x) = y

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

\frac{cos ( θ )}{sin ( θ )} = 0

sin (2 x) = sin (x), 0 \leq x < 2 π

tan (θ) = \frac{5}{5 3}

7 cos (x) = 2 + 5 cos (x)

cos (x) = 7
