How do you prove fundamental identity?
To “prove” an identity, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation. You do not plug values into the identity to “prove” anything. There are infinitely-many values you can plug in.

What is an identity in precalculus?
A trigonometric equation is any equation that includes a trigonometric function. There are two basic types of trigonometric equations: identities and conditional equations. Identities are equations that hold for any angle. Conditional equations are equations that are solved only by certain angles.

How do you do identities?
An identity is an equation which is always true, no matter what values are substituted. 2 x + 3 x = 5 x is an identity because 2 x + 3 x will always equal regardless of the value of . Identities can be written with the sign ≡, so the example could be written as.
