Differentiate Parametric Equations

Examples, videos, activities, solutions and worksheets that are suitable for A Level Maths.

Parametric equations of curves and conversion between Cartesian and parametric forms.
Students should be able to find the area under a curve given its parametric equations.

Core 4 Maths A-Level Edexcel - Parametric Equations (1)
An introduction to parametric equations.
Examples:

1. The diagram shows a sketch of the curve with parametric equations x = t - 1, y = 4 - t². The curve meets the x-axis a the points A and B. Find the coordinates of A and B.
2. A curve has parametric equations x = at, y = a(t³ + 8), where a is a constant. The curve passes through the point (2,0). Find the value of a.
3. A curve is given parametrically by the equations x = t², y =4t. The line x + y + 4 = 0, meets the curve at A. Find the coordinates of A.
