Furthermore, be aware that trigonometric functions are periodic, meaning multiple angles can have the same ratio, though the context of the problem usually indicates the specific angle you are seeking. By applying the inverse to both sides of the equation, the angle θ is isolated on one side, allowing for the calculation of its measure in degrees.
A Guide to Trig Functions and Measuring Angles
Applying the Inverse Function The critical step to isolate the angle is applying the inverse trigonometric function, often written as sin⁻¹, cos⁻¹, or tan⁻¹. Finally, if you know the opposite and adjacent sides, the tangent function is the correct choice for your calculations.
Sine is the ratio of the opposite side to the hypotenuse, cosine is the ratio of the adjacent side to the hypotenuse, and tangent is the ratio of the opposite side to the adjacent side. After calculating the ratio, you have a numerical value that represents the trigonometric function of the angle, but the angle itself remains unknown at this stage.
