The directions say, The helix r1(t) intersects the curve r2(t) at the point (1,0,0). Find the angle of intersection of these curves. Well here is my work, and I'm stuck, how am i suppose to find the dot product of these 2 vectors once i take the derivative? the sin(1) is not a pretty number, and the book gets an asnwer of Pi/2 i think. What did i do wrong? Thanks.
