If I understand your notation correctly, you want the 725th derivative of sin x ??
1st derivative of sin x = cosx
2nd derivative = -sinx
3rd derivative = -cosx
4th derivative = sinx
Ahhh, we are back where we started from.
so the 5th derivative = cos x ,etc.
725 รท 4 = 181 with remainder 1
but the 724th derivative would have been sinx
so the 725th is <b>cosx</b>
