Often when you are asked to calculate the trig function of an angle without a calculator, you will be given a right triangle, and the angle you are asked about is one of the angles in the triangle. To solve these types of problems, you need to remember the acronym SOHCAHTOA. The firs...
Trig functions are equations containing the trigonometric operators sine, cosine and tangent, or their reciprocals cosecant, secant and tangent. The solutions to trigonometric functions are the degree values that make the equation true. For example, the equation sin x + 1 = cos x has the solutio...
