Work out what relationships you have, and how they can be converted to others. Then use those relationships and substitute them for other simpler ones. Often these will allow you to simplify a furtehr step. Keep going until it can't get any simpler.
Beyond that, it takes practise to notice the patterns and straight-up memory to know what turns into what.
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.
Trigonometric identities involve certain functions of one or more angles. These identities are useful whenever expressions involving trigonometric functions need to be simplified.
Just as with any other identity, a trigonometric identity is a trigonometric statement (other than a definition), which is true for all values of the variable or variables.
Yes, this is a perfectly legitimate thing to do in the trigonometric functions. I will solve all your math problems. Check my profile for more info.
They can be used to simplify expressions so that the solutions can be found more easily.
Use the trigonometric relations and identities.
Use trigonometric identities to simplify the equation so that you have a simple trigonometric term on one side of the equation and a simple value of the other. Then use the appropriate inverse trigonometric or arc function.

Yes. Trigonometric identities are extremely important when solving calculus equations, especially while integrating.
Trigonometric identities are trigonometric equations that are always true.
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.

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.
