The exact value of sin 22.5 is 0.382683432
By using trigonometric identities find the value of sin A if tan A a half?
The value of tan A is not clear from the question.However, sin A = sqrt[tan^2 A /(tan^2 A + 1)]
What is the value of sin 24 degrees?
The exact value is 0.40673664.
What is the exact value of sin 405?
sin(405) = square root of 2 divided by 2 which is about 0.7071067812
Using exact values find the numerical value of sin 30 degrees cos 240 degrees plus sin 210 degrees sin 300 degrees?
SQRT(3)/4 - 1/4
What is exact value sin480degrees?
sin 480° is equal to sin 60°, which is sqrt(3)/2 or approximately 0.866.
What is the half angle formula to find the exact value for tan 165?
tan u/2 = sin u/1+cos u
What is the value of sin60?
sin(60 degrees) = 0.8660 approx. The exact value is sqrt(3)/2.
What are identities in algebra?
An equation in which the variable(s) can take any value and it is still true. ex. cos(x) = cos(-x) sin(x) = -sin(-x) The above equations are true for any real value of x. Identities are sometimes written with a "triple equals sign", as in 3 parallel lines rather than 2.

How to find the exact value of arc sine and cosine and tangent?
mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
