... Any one-to-one function has an inverse. A function is one-to-one if no two ordered pairs in the function have the same second component. In other words, one-to-one functions do not have any repeated values. Consequently, y sin x is not one-to-one. A quick test for one-toone correspondence is the h ...

The addition formula for the exponential function is valid for complex numbers as well as real numbers: for any comple ...

It takes a thief: Lifted Lesson Jennifer Edwards
... Recall that manipulatives are often useful in relating concrete information to a concept that is more abstract. Since we spent a short amount of time looking at factoring before, let’s try an alternate way of looking at it. First, using either Algebra Tiles or graph paper or the Edy tiles attached, ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
