simplify sin(A-pi)-cos(A-pi)

simplify

sin (A - π) - cos (A - π)

- sin (A) + cos (A)

Solution steps

sin (A - π) - cos (A - π)

Rewrite using trig identities

= - sin (A) - cos (A - π)

Rewrite using trig identities

= - sin (A) - (- cos (A))

Apply rule

- (- a) = a

= - sin (A) + cos (A)

- sin (- θ)

sin (arccos (\frac{x}{10}))

sin^{2} (6 0^{\circ} + x)

2 sin (1500 t - (\frac{π}{2}))

\frac{2}{n ^{2} π} cos (nπ)
