Webcos A = Adjacent side/Hypotenuse = AC/AB. tan A = Opposite side/Adjacent side = BC/AC. We can derive some other sin cos tan formulas using these definitions of sin, cos, and tan functions. We know … WebThe trigonometric addition formulas can be applied to simplify a complicated expression or find an exact value when you are with only some trigonometric values. For instance, if you want the Sine of 15 degrees, you can use a subtraction formula to calculate sin(15) as sin(45-30). In the same way, you can also find the value of cos 15 and tan 15.

For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
