Show how the function y = e^(-x) sin x could represent damped oscillation. a) Determine the local extreme for a sequence of wavelengths. b) Show that the local maxima represent exponential decay.

Two forces act on an object at 20 degree to each other. One force has a magnitude of 200N, and the resultant has a magnitude of 340N. Determine the magnitude of the second force and the direction it makes with the resultant.
