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.
What does angle equals x mean?
The expression "angle equals x" typically means that the measure of the angle is equal to a specific value represented by the variable x, which is often expressed in degrees or radians. This can be used in various mathematical contexts, such as geometry or trigonometry, to solve for unknown angles in equations or geometric figures. Essentially, it indicates that the angle can be quantified or defined by the value of x.

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 sgn function in trigonometry?
The sign function is used to represent the absolute value of a number when used in trigonometry. It is also referred to as the signum function in math.
