simplify sin(θ)+sin(θ+2pi)+sin(θ+4pi)

simplify

sin (θ) + sin (θ + 2 π) + sin (θ + 4 π)

3 sin (θ)

Solution steps

sin (θ) + sin (θ + 2 π) + sin (θ + 4 π)

Rewrite using trig identities

= sin (θ) + sin (θ) + sin (θ + 4 π)

Rewrite using trig identities

= sin (θ) + sin (θ) + sin (θ)

Add similar elements:

sin (θ) + sin (θ) + sin (θ) = 3 sin (θ)

= 3 sin (θ)
