B0B

In the beginning of the unit, everything was fine and understandable. The work in the HW got more challenging and harder to follow. The questions involving real life problems were difficult. Sometimes it was just a matter of obtaining the formula and differentiating it out. In some steps i would forget to leave a unit (eg. 4pi r³h, i would forget to leave the h). I'm going to review and make some revised notes for the parts of the unit i did not understand. I have to sharpen mostly the last chunk of the unit =T.
