Keep reading this article to learn more about trigonometric functions and the trig identities that relate them. Trig functions are functions that take an angle as the argument. We define these functions by using the angle of a right triangle that is inserted in a unitary circle. Then, we relate that angle to the sides of such a triangle. As the right triangle is circumscribed in a unit circle, the length of its hypotenuse equals the circle's radius which equals one unit. Sine and cosine are the fundamental trigonometric functions arising from the previous diagram:. We can rotate the radial line through the four quadrants and obtain the values of the trig functions from 0 to degrees , as in the diagram below:.

You are here Ex 8. How do we remember them? The sine law states that the sides of a triangle are proportional to the sine of the opposite angles. The sine function of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side and the formula is given by. Login To View Results.
