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 Difference identity:

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

= cos (θ - θ^{2})

cos (x - \frac{7 π}{4})

sin (- x) cos (- x) csc (- x)

sin (arccos (3 x)) d x

\frac{y}{2 sec ( x + \frac{π}{2} )}

28 sin (150 π t + 0.1)
