Easy Ways To Handle Trigonometry Homework Problems
Trigonometry is one of the more complex math’s one must tackle because of its extensive use throughout Calculus and other higher math’s. Many formulas exist that one must keep in mind at all times and maintain focus on the answer that will result. Throughout the years, people have been attempting to master the art that is math and find tips and tricks that would help in the case of this. Below are some helpful tips and guidelines to follow that have been proven to help so many in their coursework.
SOH CAH TOA
- Sine = Opposite ÷ Hypotenuse
- Cosine = Adjacent ÷ Hypotenuse
- Tangent = Opposite ÷ Adjacent
- Don’t get frustrated.
- Check the other side and try it out. They are normally equal and so proving one side will help with the other side.
- Keep them in mind always and if they are not memorized, it is normally best to keep a “Cheat Sheet” around for reference when working on problems.
- Figure out which side is simpler and which side is more complicated.
- Solve the simpler one first. Finding the answer for one side will help you find the answer for the opposite side.
- Consider combining fractions to make one single fraction to solve, or split up a larger fraction (two or more terms in the numerator) to make a larger fraction simpler to solve.
- Squaring anything should be avoided as much as possible. If you must, look for extraneous values.
- Convert EVERYTHING to sin’s and cos’s
- Sin x = csc x
- Cos x = sec x
- Tan x = cot x
- NEVER have a 0 in the denominator. This is a golden rule in any math circumstance.
- Domains don’t change. If you managed to have a new domain, look and see if there were any mistakes you could have made.
- When a solution comes out, always be sure to double check your work. It is imperative that you ensure you have completed the work correctly.
- When you get confused, feel free to contact your professor. Sometimes, just hearing something said again in a different way is all you need to figure something out. Asking questions never hurts.
When you are stuck:
Know all your formulas and identities!
Remember which equations are equal
