Trigonometric Functions: Soh-Cah-Toa: shows how to relate the sides of a right triangle using the hypotenuse, adjacent and or opposite sides

Sine, Cosine, Tangent, explained and with Examples and practice identifying opposite, adjacent sides and hypotenuse

Trigonometry Study Flash Cards - This small set of 18 cards provides a quick reference of basic trigonometric information for the math student. Each card (but one) shows an angle with its degree and radian value, its location on the unit circle, the reference angle, and the sin, cos, and tan value of the angle.    The mnemonic "All Students Take Calculus" is represented behind the unit circle with the letters A, S, T, and C to remind students which quadrant specific trig values are positive.

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.

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).
