Part of a cross-country skier's path can be described with the vector function r = <2 + 6t 2 cos(t), (15 β t)(1 sin(t))> for 0 β€ t β€ 15 minutes, with x and y measured in meters.
The derivatives of these functions are given by xβ²(t) = 6 β 2sin(t) and yβ²(t) = β15cos(t) + tcos(t) β 1 + sin(t).
Find the slope of the path at time t = 4. Show the computations that lead to your answer.
