How to Solve Trig Ratios of General Angles? (+FREE Worksheet!)

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. WebInverse trigonometric functions are the inverse ratio of the basic trigonometric ratios. Here the basic trigonometric function of Sin θ = x, can be changed to Sin-1 x = θ. Here x can have values in whole numbers, decimals, fractions, or exponents. For θ = 30° we have θ = Sin-1 (1/2). All the trigonometric formulas can be transformed into ... sid meres civilization 6
