expand (sin(a)+cos(b))(sin(b)+cos(a))

expand

(sin (a) + cos (b)) (sin (b) + cos (a))

cos (a) sin (a) + cos (b) sin (b) + cos (a - b)

Solution steps

(sin (a) + cos (b)) (sin (b) + cos (a))

Apply FOIL method

(sin (a) + cos (b)) (sin (b) + cos (a)) : cos (a) sin (a) + cos (b) sin (b) + cos (a - b)

= cos (a) sin (a) + cos (b) sin (b) + cos (a - b)

p^{\frac{1}{4}} (p^{\frac{3}{4}} + 3 p^{\frac{7}{4}})

A (- 2, 22) B (13, - 19)

x (x + 1) (x + 2) (x + 3) + 1

\frac{π t ( 3 + 2 n )}{6}
