Video tutorial illustrates one of the six basic trig ratios, the secant ratio. [4:39]

Worked example using trigonometry to solve for the lengths of the sides of a right triangle given one of the non-right angles.

Problems address the equation of a circle, basic trignometry.

Worked example where we walk through finding the major trigonometric ratios.

Video introducing the basic trigonometry ratios sine, cosine, and tangent.

In this lesson, you will learn how the ratios of certain sides of the triangle determine the tangent value of a particular angle by using properties of similar triangles. [2:13]

This video explains how to solve trigonometric equations involving multiple angles. [18:44]

Trigonometric equations are just equations that feature the trigonometric ratios such as sine and cosine on the variable "x". Because of the presence of these trigonometric functions, solving these equations becomes a little more...
