How do you know if a triangle has 2 solutions
WebIn general, if you know the trig ratio but not the angle, you can use the corresponding inverse trig function to find the angle. This is expressed mathematically in the statements below. Misconception alert! The expression \sin^ {-1} (x) sin−1(x) is not the same as \dfrac {1} {\sin (x)} sin(x)1. In other words, the -1 −1 is not an exponent.
