Jessica and Matthew are running toward the point P along the straight paths that make a fixed angle of 0 (Figure 1). Suppose that Matthew runs with velocity va (m/s) and Jessica with velocity v, (m/s). Let f(æ, y) be the distance from Matthew to Jessica when Matthew is æ meters from P and Jessica is y meters from P.

Jessica and Matthew are running toward the point P along the straight paths that make a fixed angle of e
(Figure 1).
Suppose that Matthew runs with velocity va (m/s) and Jessica with velocity v, (m/s).
Let f(x, y) be the distance from Matthew to Jessica when Matthew is æ meters from P and Jessica is y meters
from P.
FIGURE 1
• Show that f(x, y) = Væ2 + y? – 2xy cos 0.
• Assume that 0 =
T/3. Use the Chain Rule to determine the rate at which the distance between Matthew and
Jessica is changing when
x = 25, y = 22, va = 2 m/s, and vz = 3 m/s.
