How do trig functions work
WebLearn how to use trig functions to find an unknown side length in a right triangle. We can use trig ratios to find unknown sides in right triangles. Let's look at an example. Given \triangle … WebStep 1 Find which two sides we know – out of Opposite, Adjacent and Hypotenuse. Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question. Step 3 For Sine calculate Opposite/Hypotenuse, for Cosine calculate Adjacent/Hypotenuse or for Tangent calculate Opposite/Adjacent.
