Practice Problems: 1. Find the following antiderivatives: (a) fw+1+tanh (5)411: $2 (b) /5\"(2 cot 53)(1 csc 53) d3 112log3: (C) m/loga: - logim dz 2. As part of a skydiving course, a diver jumps out of a plane 64 ft above the ground with an initial velocity of 48 ts. Assuming that the only force acting on the diver is acceleration due to gravity (given by 32 fsz), determine the velocity of the diver at the moment the diver lands on the ground
