By using trigonometry identities find the value of a sin A if TAN A equals half?
Josepr
tan(A) = 1/2
sin(A)/cos(A) = 1/2
sin2(A)/cos2(A) = 1/4
sin2(A)/[1 - sin2(A)] = 1/4
sin2(A) = 1/4*[1 - sin2(A)]
5/4*sin2(A) = 1/4
sin2(A) = 1/5
sin(A) = ±sqrt(1/5) = ±sqrt(5)/5

What are identities trigonometry?
Identities are "equations" that are always true. For example, the equation sin(x) = cos(x) is true for x = pi/4 + kpi radians where k is any integer [ = 45 + 180k degrees], but for any other value of x the equation is not true. By contrast, the equation sin2(x) + cos2(x) = 1 is true whatever the value of x. This is an identity.
How do you find the value of an angle?
You could measure it using a protractor, derive it from basic geometric properties (for example angles of a regular polygon), or calculate it using trigonometry.
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.

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)]
