Remembering exact trig values
WebA right triangle has a hypotenuse of length 10 and a leg of length 6. Find the exact values of the six trigonometric functions of the angle \(\theta\) if \(\theta\) is adjacent to the leg of length 6. Solution. To be able to find these values, the first thing you will need to do is figure out what the side length is for that missing leg. http://tutor.trevor-mendham.com/mathstips/exactvalues.html
