Basic Differentiation Tutorial. Differentiation The process of finding the gradient or slope of a function is the differentiation. We used to find the gradient of a straight line, just by dividing the change in 'y' by change in 'x', in a certain range of values. However, when it comes to a curve, it is not easy to find the gradient or slope as the very thing we want to measure, keeps changing from point to point. we have to draw tangents at all those points and then find the gradients individually. The following animation illustrates just that.

If we stick to this method we will have to draw hundreds, if not thousands, of tangents to find the gradient at various points of the curve; enough work to put off someone doing maths for decades! Good news is that there is a method that comes to our rescue. If y = xn then dy/dx = nxn-1 That means, if a curve is in the form of y = xn , its gradient at any point is given by nxn-1 . Understanding Exponents (Why does 0^0 = 1?) We’re taught that exponents are repeated multiplication. This is a good introduction, but it breaks down on 3^1.5 and the brain-twisting 0^0. What is a Logarithm? A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2 because. Introduction to Logarithms. In its simplest form, a logarithm answers the question: Approaches that try to avoid memorization. Algebra 1 Math Course. GeoGebra Calculus Applets. Unit Circle. The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here. Sine, Cosine and Tangent Because the radius is 1, we can directly measure sine, cosine and tangent. What happens when the angle, θ, is 0°? Trigonometry - Wikibooks, open books for an open world.
