Solution steps

One step at a time

cos²(x)=sin(x)

Subtract sin(x) from both sides

cos²(x)−sin(x)=0

Rewrite using trig identities

1−sin(x)−sin²(x)=0

Solve by substitution

sin(x)=−1+√52 , sin(x)=√5−12

sin(x)=−1+√52 : No Solution

sin(x)=√5−12 : x=arcsin(√5−12 )+2πn, x=π−arcsin(√5−12 )+2πn

Combine all the solutions

x=arcsin(√5−12 )+2πn, x=π−arcsin(√5−12 )+2πn

Show solutions in decimal form

x=0.66623…+2πn, x=π−0.66623…+2πn
