Question

solve sin(5pi/12); use pi/4+pi/6

Answer 1

pi/4 + pi/6 = 5pi/12

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

so
sin(pi/4 + pi/6) =...?

Answer 2

√2/2 *√3/2 + √2/2 * 1/2
6/4 = 3/2 + √2/4 = 6√2/4 ??

Answer 3

√2/2 *√3/2 = √6/4

Answer 4

@Algebraic! so the answer is not √6+√2 / 4?

Answer 5

that's the right answer.

Answer 6

thank you
