Expansion of sin3x

WebFirst, evaluate the integral. b n = 1 π ∫ − π π sin 3 ( t) sin ( n t) d t = 12 sin ( π n) n 4 − 10 n 2 + 9. Now, you can see that, the only non zero values for b n comes from n 1 and n 3 which they give the values. b 1 = 3 4 a n d b 3 = − 1 4. Note that, a n = 0. So, your final result is the well known identity. WebStep 1. Maclaurin series coefficients, ak can be calculated using the formula (that comes from the definition of a Taylor series) where f is the given function, and in this case is sin ( x ).
