Yeah sure ! Apparently i haven't seen much cases in math where it gave me trouble . And when i was taught this theorem i was really excited coz before that, my teacher forced me to solve by expanding and stuff .

True. But in many cases it either gets highly simplified or less complex. Every question has its own easy approach, and i have enough practice on this topic to "see" through these questions. I used it in this particular question bcoz it gave away answer with very simple mental calculation. So...

I prefer L' hopital rule in such cases. The given question is 0/0 indeterminate form , so just apply it and you will get answer ( which is 30 , right? ) without even touching your pen .

You mean that the motion of the two pads is not a mirror image of each other ?? I can't imagine that ...

How is that possible ? Both of them were switched on simultaneously , so both of them will be at rest and at motion at same times.

The author made the slope too small ...so i think he meant us to treat both of the pads in the same manner.

Homework Statement Two rubber pads are affixed at the bottom of a box and the assembly thus formed is placed on a uniform slope of inclination 0.5 degrees. Coeff of friction is 0.60 between the pads and the plane. Two electric motors installed in the box can make the pads move back and forth...
