When you are faced with an integral which is a product, such as x.cos(x), you may be able to integrate it by parts. The statement of the integration by parts is that:
∫u(dv/d...
A quadratic expression is of the form ax2+bx+c. It is often useful to know what values of x will make the expression equal to 0; these are known as the roots of the equation. An easy way of...
Current is the rate of flow of charge in a circuit; you can imagine the flow of electrons as water flowing through a pipe. If the pipe splits into two, some of the flow will go through one pipe and som...
Parametric equations are a set of equations which both depend on the same variable, such as t. An example of this would be:
x = 2t2+1 and y = t4-2
