LIATE stands for: Logarithmic Inverse trigonometric Algebraic Trigonometric Exponential The heuristic says: when there are two factors in the integrand, choose u as the one furthest to the left in LIATE and choose dv as the one furthest to the right. Example... ... Here is algebraic, is exponential. So use ... Here is algebraic, is logarithmic. So use Try this...
