First derivative Given a parametric equation: x = f(t) , y = g(t)It is not difficult to find the first derivative by the formula: Example 1 If x = t + cos t y = sin t find the first derivative. Solution Second derivative However it is not true to write the formula of the second derivative as the first derivative,that is, Example 2 If x = t + cos t y = sin t find the second derivative. Analysis Solution For more serious learner The formula for the second derivative of parametric equation is given by:
