Find the first four terms of Taylor Series for the function f (x) = \sqrt{x} at x = 9 or centered at x = 9 . Use the formula for Taylor series of a function f at c to compute the first three terms and the general te...
We will use the integration by parts formula:∫udv=uv−∫vduLet:- u=log(sinx) (First function)- dv=cos(2x)dx (Second function) Now, we need to find du and v:- Differentiate u: du=1sinxcosxdx=cotxdx- Integrate dv: v=∫cos(2x)dx=12sin(2x) Step 3: Substitute into the ...
