WebThis is an easy way to remember the trigonometric ratios. Sine equals opposite over hypotenuse, cosine is hypotenuse over adjacent, and Tangent equals opposite over … WebOnce you are there if x1 > π take the result as sin(x1) = − sin(x1 − π) reducing it to x2 = 0, π. Now if x2 > π 2 calculate the result as sin(x2) = sin(π − x2). So all this above is easily shifting it all to x3 = 0, π 2 If needed use further sin(x) = 2sin(x 2)cos(x 2) with cos(x 2) = √1 − sin(x 2)2 in case x3 > 1.

In the last section, Sine, Cosine, Tangent and the Reciprocal Ratios, we learned how the trigonometric ratios were defined, and how we can use x-, y-, and r-values (r is found using Pythagoras' Theorem) to evaluate the ratios. Now we'll see some examples of these ratios. Finding Exact Values of … WebTrigonometric ratios table helps to find the values of trigonometric standard angles such as 0°, 30°, 45°, 60° and 90°.
