1. To verify a trig function means to break down an equation of trig functions to the smallest, most simplest trig function possible. that means to put all our knowledge of previous math to work. All the information we learned from the Unit Circle are being tested in this unit. All equations must break down to one trig function. That is your goal!
2. The tips and tricks that i have found helpful to me is the Unit Circle and the identities that we have had to memorize. The Unit Circle's points and degrees are a part of Units 1-5. The trig identities are what come to finding our answers much faster than any other method.
3. To begin breaking down a trig function, i first look to see if it is possible to split or substitute anything into the equation (You look for the fastest way to break down your equation). Next we see if any identities are found or can be made with what we have broken down. If not, we continue with what we have, either multiply or divide functions. The final thing i look for is the possibility if the function can be substituted, distributed, or identified (usually will be one of these).
