In this lesson we will derive trigonometric ratios for sine, cosine and tangent. Definitions will be given for cosecant, secant and cotangent. Definition: If we consider angle ABC (labeled ), we can define the hypotenuse to be side BC, the adjacent side (next to angle ) to be side AB and the opposite side (opposite the angle ) to be side AC.
