You'll probably never use it again once you've done your exam, but hey ho... such is life. Do Algebraic Division by means of Subtraction ^2x 3 - 3x 2 - 3x + 7h ' ^ x - 2h = ? The trick with this is to see how many times you can subtract ^ x - 2h from ^2x 3 - 3x 2 - 3x + 7h . The idea is to keep subtracting lumps of ^ x - 2h until you’ve got rid of all the powers of x. Do the subtracting in Stages At each stage, always try to get rid of the highest power of x. Then start again with whatever you’ve got left.
2 Finding Tangents and Normals Because the gradient of the normal multiplied by the gradient of the curve must be –1. And the equation of the normal is y - y1 = - 3^ x - x1h . 2 Finally, since the normal goes through the point (4, 4), the equation of the normal must be y - 4 = - 3^ x - 4h , or after rearranging, y = - 3 x + 10 . 2 2 of the curve -1 for a normal: gradient of the curve 3) Write the equation of the tangent or normal in the form y – y1 = m(x – x1), or y = mx + c. 4) Complete the equation of the line using the coordinates of a point on the line.
Finding the equation of a line Through Two Points If you get through your exam without having to find the equation of a line through two points, I’m a Dutchman. Example Find the equation of the line that passes through the points (–3, 10) and (1, 4), and write it in the forms: y - y1 = m ^ x - x1h y = mx + c ax + by + c = 0 — where a, b and c are integers. You might be asked to write the equation of a line in any of these forms — but they’re all similar. Basically, if you find an equation in one form — you can easily convert it into either of the others.
