Great tutorials. Tell me why I could comprehend this in just 3 videos while struggling to comprehend in class? This method is so much more powerful than the traditional ways.

To check to make sure your graphing is correct would you plug in your x-values and solve? Thank you so much by the way I was freaking out until I found your video.

is the phase shift pi over 3 or negative pi over 3?? because its negative pi over 3 over 1 equals negative pi over 3....

In the second problem: y = 5 cos (4x + pi), why the phase shift is negative pi/4? How did it become negative? Can you please explain?

isn't the phase shift -c/b? that is what i learned at least

in the LEP and REP the answers would be x=pi/4 and x=3pi/4... you didn't include the negative sign when you substituted it in...
