If I am asked to find all solutions to 3 decimals of a trig function, and I know how to get each functions period, how to I get a common period so that I have the distance?
Thanks
For instance if I had:
=
I know that has a period of
and that has a period of just
but when I writing it in terms of what I get from graphing it on my calc and then putting at the end what would be the average or how could I find the ?
I want to know how to do this for future reference...simply solving the equation won't help
Thanks so Much!!!
I see what you're up to. In this case both of the functions (sin(3x) and cos(x)) are periodic on so any solutions will also have a period of . (See the graph below.)
If you have something like
then we have to note that both functions are periodic on so the solutions will have a period of .
