|dw:1351525495611:dw|

2. ksaimouli Group Title

this is deferentiable or not how can i say /

@Callisto

4. ksaimouli Group Title

how can i figure out whether this function is differentiable or not

5. zepp Group Title

This function is differentiable only at where this function exists

6. zepp Group Title

The derivative of this function would be $\large \frac{d}{dx}(x^{\frac{2}{5}})=\frac{2}{5x^{\frac{3}{5}}}$

7. zepp Group Title

Differentiable from 0 to $$+\infty$$

8. zepp Group Title

Wait, I'm not sure :/

Hmm... A function is differentiable when the left hand limit = right hand limit as x-> c, I think? Of course, that function must be continuous. Perhaps you can read this: http://www.math.wfu.edu/tutorials/Math111/ContinuityandDifferentiability.pdf Check the part differentiability.

10. ksaimouli Group Title

nope can any one explain how to graph without taking points

11. ksaimouli Group Title

this one has corner so not differentiated
