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 + π) - (- cos (A))

Rewrite using trig identities

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

Apply rule

- (- a) = a

= - sin (A) + cos (A)

sec (A) (csc^{2} (A) - 1)

sin (nπ) - sin (0)

sin (arccot (3 x))

- sin^{2} (18 0^{\circ} + x)

cos (arctan (\frac{4}{3}) + p in)

What is sin(A+pi)-cos(A+pi) ?
