This somehow seems easy, but I cannot get the jist of it. f(x) = x^3 - x^2 - 4x + 4 The point (a,b) is on the graph of f and the line tangent to the graph at (a,b) passes through the point (0,-8) which is not on the graph of f. Find the values of a and b. okay so, I've spent about an...

Alright this is my first post so let me just say hi! The problem reads something like this... There is a table with a block, m2, resting on the surface. Another block, m1, is resting on top of the first block. m2 is connected to a string which goes over the table top, through a pulley, and...

Hi everyone, I need some advice on what to do about my AP Physics course. Last year when I was taking my CP Physics course as a junior in high school I got sick (am still battling now) and I self taught 2/3 of the material because I wasn't able to attend school regularly until the last...
