simplify cos(θ^1+θ^2)

simplify

cos (θ^{1} + θ^{2})

cos (θ + θ^{2})

Solution steps

cos (θ^{1} + θ^{2})

Rewrite using trig identities

= cos (θ) cos (θ^{2}) - sin (θ) sin (θ^{2})

Use the Angle Sum identity:

cos (s) cos (t) - sin (s) sin (t) = cos (s + t)

= cos (θ + θ^{2})

4 sin (4 5^{\circ} + x) + 3

sin (arccos (sin (x)))

- sin (2 x + \frac{π}{4})

sin (x - \frac{π}{4}) - 1

\frac{1}{cot ( θ ) sin ( - θ )}
