The three sides of a right-angled triangle have special names. The hypotenuse (\(h\)) is the longest side. It is opposite the right angle. The opposite side (\(o\)) is opposite the angle in question ( ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...

This favorite lesson explores a novel geometric approach to determine the exact-value trigonometric ratios for angle measures of 22.5 degrees, 67.5 degrees, 15 degrees, and 75 degrees. Journal ...
