Use integration by parts to show that e2x Se²x s sin(x) dx 0.2 = - 5 Hence determine the exact value of 2x e²x sin(x) dx Jo [2 sin(x) cos(x)] Use the standard McLaurin series for e* and sin(x) to determ the Mc Laurin expansion for e²* sin(x) up to the term in x³. Hence determine an approximate value for -0.2 - e2x sin(x) dx How does your approximation compare to the exact result yo found in a)?
