Question

The coefficient ofx8 in the expansion of sin(x?) is​

Answer 1

Answer:

In order to use Taylor's formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin�(x) = cos(x) sin��(x) = − sin(x) sin���(x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.
