Using the Pythagorean theorem (a2+b2=c2), we can find the 3rd side of a triangle if we know the other two sides and if we know we have a right triangle. If we use trig functions as well (assuming we still have a right triangle), we can find any angle or any side as long as we have two angles, two sides, or an angle and a side (aside from the right angle).

Define the tangent, sine, and cosine ratios for both the acute angles in a right triangle. State and apply the relationship that exists between the trig functions of an acute angle of a right triangle and those of its complement. Recognize the secant, cosecant and cotangent functions as the inverse functions of sine, cosine and tangent.

We want to be able to find these angles but we only know the lengths of the sides of the right triangle. Using SOHCAHTOA (as was previously discovered), we will find the missing angles. Definition: We need to know that given, we can find A by taking This means that This definition will also be true for any of the other trigonometric functions.
