simplify sin(t-1/4 pi)

simplify

sin (t - \frac{1}{4} π)

sin (- \frac{π}{4} + t)

Solution steps

sin (t - \frac{1}{4} π)

Rewrite using trig identities

= \frac{2 sin ( t ) - 2 cos ( t )}{2}

Factor

- cos (t) 2 + sin (t) 2 : 2 (- cos (t) + sin (t))

= \frac{( - cos ( t ) + sin ( t ) ) 2}{2}

Rewrite using trig identities

= sin (- \frac{π}{4} + t)

sin (π t) \cdot sec (π t)

cos (arccos (v))

cos (\frac{π}{4} + θ)

sec (θ - \frac{π}{4})

tan^{3} (- 7 j)
