Values of Sin 15, cos 15 ,tan 15 ,sin 75, cos 75 ,tan 75 of degrees can be easily find out using the trigonometric identities. Also there can be many ways to find out the values. Lets explore few ways. Value of sin 15 degrees. Method 1 ( using sin 30) Caution 2.14. We must use the sides of a right triangle to calculate the sine of an angle. For example, in the triangle at right, sin θ = 47 sin θ = 4 7, because ABC A B C is a right triangle. It is not true that sin θ = 57 sin θ = 5 7, or sin θ = 67 sin θ = 6 7. In this chapter, we consider only right triangles. For Example : tan 22.5° = √2 - 1 sin 18° = (√5 -1)/4 I am Not Asking For The Values, Stack Exchange Network Stack Exchange network consists of 183 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. For example, since the circumference of the unit circle is 2π, an arc of length t = π will have it terminal point half-way around the circle from the point (1, 0). That is, the terminal point is at (1, 0). Therefore, cos(π) = − 1 and sin(π) = 0. Exercise 1.2.1. Determine the exact values of each of the following: Microsoft Word - Table of Exact Trig Values.doc.
