Unlike equations (or inequalities), identities are always true. It is, therefore, not possible to solve them to obtain values of the variable(s).
You make them less complicated by using trigonometric relationships and identities, and then solve the less complicated questions.
In trigonometry, identities are mathematical expressions that are true for all values of the variables involved. Some common trigonometric identities include the Pythagorean identities, the reciprocal identities, the quotient identities, and the double angle identities. These identities are used to simplify trigonometric expressions and solve trigonometric equations.
To solve trigonometry problems easily, make sure you have a good understanding of the basic trigonometric functions (sine, cosine, tangent) and their properties. Practice using trigonometric identities and formulas to simplify expressions. Visual aids such as diagrams can also help in understanding and solving trigonometry problems more easily.
Trigonometric identities are trigonometric equations that are always true.
You can solve for sin18 by making use of trigonometry.
by calculating the angles
It requires more than Trigonometry to solve these issues. The answer is simply : It cannot.

sin^2 (feta) + cos^2 (feta) = 1 sin (feta) / cos (feta) = tan (feta)
Typically, the pre-requisite for calculus is algebra and trigonometry. These are usually universally required because you need these skills to actually do the mathematics of the calculus. There are a lot of identities in trigonometry that you will wish you could remember when you are working with calculus of trigonometric functions.
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
