Trigonometric Ratios Of Special Angles Activity

Trigonometric Ratios Of Special Angles Activity. This lesson shows how to use the unit circle to evaluate trigonometric ratios of special angles and an example using the special angles. In these lessons, we will learn the trigonometric functions of the special angles 30˚, 45˚, 60˚, and 90.

Trigonometrical ratios of complementary angles. Let's practice recalling the values of trigonometric ratios of some special angles. Let abc be an equilateral triangle whose sides have length a (see the figure given below).

With proper understanding, they are very easy to use as well!

Putting together the trigonometric ratios and the coordinates of the points on the circle, which represent the lengths of the legs of the triangles, (δx,δy) if you memorize the special right triangles, can determine reference angles and know where the ratios are positive and negative you can put the.

Can i use the same method to find ratios of other angles too? The fraction of opposite side over adjacent side is called tangent (abbreviated as tan), the fraction of adjacent side over hypotenuse is.
