easy angle thing
ok so i have this list of questions like this one:
find the least positive value of B for which sin(A-B)=cos(A+B)
using translation, odd, periodic properties, etc.
the problem is i totally forgot how to work these out! i know there is a simple method to work this out without staring continually at the sin and cos graphs, i just need a little reminder. thanks
umm i got most of it but at the level i'm at the n is not really appropriate, could you kinda simplify that?
Dear furor celtica,
