By multiplying the appropriate Taylor series about c =0, compute the first four terms of the Taylor series about c =0 for f ( x ) = e x cos x . Hint:...

1. By multiplying the appropriate Taylor series about c = 0, compute the first four terms of the Taylor
2. series about c = 0 for f(x) = e−x cosx.
3. Hint: It is not necessary to do any differentiation to do this problem.
