Hi
After expressing an equation in the form RSin(x-alpha), how do i find the 'greatest and least possible values'
I have 2sinx-3cosx = rt13(x-0.983)
Write down the greatest and least possible values of 1 + 2sinx-3cosx
The write down bit signifies to me that this shouldnt take too long.
im not sure what to do...???
thanks
