Sines are positive in the first and second quadrants.
So 2x-1= .2526 or pi-.2426 or 2pi+.2526 or 3pi-.2426 etc
So a formula for these answers is npi+(-1)^n(.2526)
Set f(x) = g(x) and find the principal and
f(x) = sin (2x − 1), g(x) = 1/4.
So I have no trouble finding the principal solution...
Now how on earth do I about solving for the symmetry solution without cheating using a graph? I know, or at least think, you have to relate it to a minimum or maximum, but this becomes difficult without a graph because I'm not entirely sure where the solution I have is located. How do you solve this with just plain equations? I'm reviewing precalc/calc after a 5 year hiatus and only have myself and an old text book and the text book isn't much for help.
