For problems 1 and 2, determine the interval of convergence for the indicated power series. 1. (10 points) (-1)"(2 - 3)n M n= 1 For problems 4 and 5, determine the slope of the tangent line to the curve at the indicated point. If the slope is undefined, state that it is undefined. 4. (10 points) x = 4 + sin(t), y = t cos(t), t = 1/4 5. (10 points) r = 3(1 + cos(20)), 0 = 1/2
