Sum and Difference Formulas for Sine And Cosine sin(A + B) (Manipula Math) sample problems 1) Find the exact value of cos 15 o Solution: Think of two angles that you know the value of, that either add or subtract and give you 15. There are many. One that comes to mind is 45 and 30. let a = 45 and b = 30 Use the above formula for the difference of the cosine cos 15 = cos(45 - 30) = cos 45... 31 thoughts to “Find Value of Sin and Cos using Fingers” Sin 30 is 1/2 while Cos 30 is (sqrt 3) /2. The sqrt applies only to 3 and not to 2. Similarly for 45, both sin and cos is 1 / (sqrt 2). Needs a bit of tweaking? Reply.
