<u>Trigonometric Ratios</u>
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).
The ratios are valid only in right triangles, or when one of the internal angles is 90°.
Take any of the acute angles as a reference, and the largest side as the hypotenuse, then:
The missing side of the triangle x can be calculated by using Pythagora's Theorem:
Solving:
For the angle marked as θ:
