How To: Graph a system of linear equations

Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line.

A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...

How To: Solve inequalities by using addition and subtraction

Khanacademy teaches us how to handle simple inequalities (less than or more than). In an equation, we usually have one solution. In problems involving inequalities, there is a whole set of answers. For instance, x minus five is less than 35. The answer for x is a whole series of numbers that when five is taken away from it, is less than 35. This equation is handled like any other equation involving an equal sign. We add five on both sides of the equation and the answer for x is any number tha...

How To: Solve complex indefinite integrals in calculus

In this video the math teacher explains the meaning of the indefinite integral formula in calculus by stating it in terms of antiderivatives. He then shows in general terms how this indefinite integral formula has a related derivative formula, i.e. if the derivative of F(x) is f(x) then the indefinite integral of f(x) is F(x) plus a constant term (C). With this general relationship the teacher takes us through three related examples where he converts a derivative formula to an integral formul...
