5sin(θ)=5cos(θ)

5 sin (θ) = 5 cos (θ)

θ = \frac{π}{4} + πn

Degrees

θ = 4 5^{\circ} + 18 0^{\circ} n

Solution steps

5 sin (θ) = 5 cos (θ)

Rewrite using trig identities

5 sin (θ) = 5 cos (θ)

Divide both sides by

cos (θ), cos (θ) \neq = 0

\frac{5 sin ( θ )}{cos ( θ )} = \frac{5 cos ( θ )}{cos ( θ )}

Simplify

\frac{5 sin ( θ )}{cos ( θ )} = 5

Use the basic trigonometric identity:

\frac{sin ( x )}{cos ( x )} = tan (x)

5 tan (θ) = 5

5 tan (θ) = 5

Divide both sides by

5

5 tan (θ) = 5

Divide both sides by

5

\frac{5 tan ( θ )}{5} = \frac{5}{5}

Simplify

tan (θ) = 1

tan (θ) = 1

General solutions for

tan (θ) = 1

θ = \frac{π}{4} + πn

θ = \frac{π}{4} + πn

θ, 2 cos (θ) = sin (θ) + cos (θ)

x, cos (x + y) + sin (x) = 0

2 sin (x - \frac{π}{4}) + 1 = 2
