Expert Answer
There is no such standard rule, here are few suggestions that have been proven useful in solving examples related to trigonometry
- Convert all sec, csc, cot, and tan to sin and cos. Most of this can be done using the quotient and reciprocal identities.
- Check all the angles for sums and differences and use the appropriate identities to remove them.
- Check for angle multiples and remove them using the appropriate formulas.
- Expand any equations you can, combine like terms, and simplify the equations.
- Replace cos powers greater than 2 with sin powers using the identities.
- Factor numerators and denominators, then cancel any common factors.
