AI Drawing Prompt Reference

Draw a curve defined by parametric equations and calculate the area enclosed by the curve. Input the functions f(t) and g(t) for the parametric equations, and the range of parameter t from a to b. First, input f(t) and g(t), then plot the parametric curve. Finally, calculate and display the area enclosed by the curve and the x-axis.
