Thank you so much! You were absolutely correct. I was really confused by the way it was explained so I didn't think to turn on radian mode. Thank you.

I've attempted to graph it, but I still could not find a minimum or maximum point within range. But aside from that, the problems assigned in the class are supposed to be done without calculators, and obviously without computer programs as well, so I have to figure out how to do it by hand...

Homework Statement Find the minimum and maximum values of x and the values of f(x) at these points if: f(x) = 10.9sin(0.7x)+2.1cos(0.7x) The range is (-.27,8.7) Homework Equations I don't know/think there are any The Attempt at a Solution I found f'(x) =...

Homework Statement A hanging 2.00-kg (19.6N) block begins to accelerate a 4.28-kg (41.94N) block on a horizontal surface. But a rope connected to the wall at 26.9 degrees brings the block to an equilibrium position. The coefficient of friction between the surface and the 4.28-kg (41.94N) block...
