11
Slopes of Parametrized Curves Usually, we write this in a different form… A parametrized curve (x(t), y(t)) is differentiable at t if x and y are differentiable at t. At a point on a differentiable parametrized curve where y is also a differentiable function of x, the derivatives dy/dt, dx/dt, and dy/dx are related by the Chain Rule: If all three derivatives exist and,

Practice Problems Find the equation of the line tangent to the curve at the point defined by the given value of t. Find the three derivatives:
