im trying to verify this identity - sin x + tan x / 1 + cos x = tan x - i get lost very easily and need the steps - can anyone help me? :yuck:
A trigonometric identity is an equation that is true for all possible values of the variables involved. It is used to simplify trigonometric expressions and solve equations.
To verify a trigonometric identity, you can use algebraic manipulations and trigonometric identities that you already know to transform one side of the equation into the other side.
The process of verifying a trigonometric identity involves using algebraic manipulations and known trigonometric identities to simplify one side of the equation until it is equal to the other side. This process is also known as proving the identity.
Some common trigonometric identities include Pythagorean identities, double angle identities, half angle identities, and sum and difference identities.
Trigonometric identities are useful in simplifying and solving trigonometric expressions and equations. They are also used in many real-world applications, such as engineering, physics, and astronomy.
