Hi I am a calc student in great need. If any1 can please help me thank u very much.
Here it is
For the func.
f(x) = { 0 x < or/and = 0
2x +1 x > 0
Proove that f(x) is not differentiable at x=0
Also
2. A two piece ladder leaning against a wall is collapsing at a rate of 2 ft/sec while the foot of the ladder remains a constant 5 ft from the wall. How fast is the ladder moving down the wall when the ladder is 13 ft long?
