Best ways to sketch sin and cos graphs.... like finding x-intercepts, (with dialations)....or even without any dialations.

Does general solutions formula work for x-ints...??  :(

Help Help....Thanks

general formula would work except if the graph has a vertical translation.

how do you use the formula, on sin and cos, -- because sin has 2??   --- ( thanks for telling of the vertical)

Those formulas should be in your book.

Remember

pick random values of n (I'd just start off with 0, then maybe 1, -1 etc etc) and make sure the final answer is in your domain.

Yeah, just make sure you don't make any arithmetic errors

Yes but you have to apply the transformations on the formula

as a general rule, don't use the general formula. approach the problem graphically.
