Now apply integration by parts to this second integral. If up = sinh (5 x), enter (9) up (h) up (Note: you still don't need a constant of integration here.) (i) Hence write the integral in the form I = wv - uquq + / vguh da : I = (j) You should notice that the integral in (i) is a multiple of the original integral, I. Hence rearrange the equation in (i) to determine the answer to the original integral, I. (Remember you should include a constant of integration here, +c) I =In this question you will use integration by parts twice. Consider the integral sin (7 x) cosh (5 x) do. Think of this as / wv dx. Let u = cosh (5x). (a) Enter v (b) Enter u' (c) Enter v (Note: you don't need a constant of integration here.) Hence write the integral in the form I = wv - / vu' dx : (d) Enter uv (e) Enter vu
