Precalculus

  • 1. Law of Sines
  • 2. Unit Circle - exact values
  • 3. Ellipse and Hyperbola Review

3.1.

Law of Sines

This is a basic draggable triangle that illustrates the Law of Sines ratios and also has a slider to substitute and compute the ratios to show that all 3 ratios wind up being equal.

Students: Here you can play with a triangle to convince yourself that the sine of each angle divided by its opposite side length remains the same throughout the triangle. Use the "Substitute and compute" slider to see the simplified values.

Algebra

  • 1. Function Transformations

5.1.

Function Transformations

Type in a parent function, such as f(x)=x^2. Adjust the sliders for a, b, h, and k to transform the function to y=g(x). Realize, a and b should never equal zero. Point P is on f(x); point Q is the transformed value. Press F11 key for full screen.

Flash Cards Multiplication

Try to beat the computer: Say it before you see it. Use the slider to get more time.
