int e^(ax)cos bxdx=

" (a) "int e^(x)cos xdx

Evaluate the following integrals: int e^(ax) cos bx dx

If u=inte^(ax)cos bx dx and v=int e^(ax)sinbx dx , show that, (a^(2)+b^(2))(u^(2)+v^(2))=e^(2ax)

Evaluate inte^(ax)sinbx dx and int e^(ax)cosbx dx by integrating each of them only once by parts.

Method of integration by parts : If u=inte^(ax)cos bx dx and v= int e^(ax) sin bx dx then (a^(2)+b^(2))(u^(2)+v^(2))=....

If u=inte^(ax)cos bx dx and v=int e^(ax)sinbx dx , show that, "tan"^(-1)(v)/(u)+"tan"^(-1)(b)/(a)=bx .
