How do you know which trig function to use
WebValues of Quadrantal Angles. When an angle lies along an axis, the values of the trigonometric functions are either 0, 1, -1, or undefined. When the value of a trigonometric function is undefined, it means that the ratio for that given function involved division by zero. Below is a table with the values of the functions for quadrantal angles. WebAngle C can be found using angles of a triangle add to 180°: So C = 180° − 76° − 34° = 70° We can also find missing side lengths. The general rule is: When we know any 3 of the …
