Half Angle Formulas: Half-Angle Formulas

When will half of the substance be gone? Using the exponential decay formula, the video finds the half-life of radium-226. The 29th installment in a 31-part series goes on to discuss that the calculations are the same independent of the...

When you graph an inequality on the coordinate plane you will get two half-planes. The line itself is called the boundary line. One of the halves is called the closed half-plane and the other half is called the open half-plane. How do...

Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...

Twenty-two problems present a variety of practice working with double-angle and half-angle formulas. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the...

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Young scholars use M&M's and a graphing calculator to collect and graph data. This activity helps them to understand exponential functions and the concept of half-life.

This page, from Eric Weisstein's comprehensive Math World site, offers information on half-angle formulas. The site includes traditional trigonometric fuctions half-angle formulas as well as hyperbolic half-angle formulas. Includes links...
