4-3 RIGHT TRIANGLE TRIGONOMETRY
Right Triangle Trig Ratios: The six right triangle trigonometry ratios are equations that show the relationship between the an angle and the ratio of any two sides of the right triangle. The six trig ratios are sine, cosine, tangent, cosecant, secant and cotangent. The reciprocal of sine is cosecant, the reciprocal of cosine is secant and the reciprocal of tangent is cotangent.
