WHAT ARE THE SIX FUNDAMENTAL TRIGONOMETRIC RATIOS? Trigonometric formulas are the six basic trigonometric ratios which establish the ratios of the lengths of the sides with each other in a right angled triangle. the three fundamental trigonometric ratios as sin, cos and tan, which their reciprocal trigonometric ratios cosec, sec and cotan are derived trigonometric ratios.

Math Trigonometry sin cos Trigonometric Hand Trick This is an easy way to remember the values of common values of trigonometric functions in the first quadrant.

Addition and Subtraction Formulas for Sine and Cosine: In a right triangle with legs a and b and hypotenuse c, and angle alpha opposite side a, the trigonometric functions sine and cosine are defined as sin(alpha) = a/c, cos(alpha) = b/c

Visualization of Euler's formula (e^ix) = cos(x)+i sin(x). (Only in here because it reminds me of the low frequency tones produced by a long skipping rope, and it's a neat animation).

This is an awesome post! really useful teaching technique for showing the graphs of sine, cosine, and tangent . maybe use blue instead of yellow for cosine though
