diffrentiation is 2 differentiate and summation is 4 summing up ...integration...
if u r given a large part and u r considering only the infinitely small part ..use diff...and thereafer if u want 2 consuider the effect on the entire part use integration.....

The derivative is a measurement of how a function changes when the values of its inputs change. For a real-valued function of a single real variable, the derivative at a point equals the slope of the tangent line to the graph of the function at that point.

Summation is the addition of a set of numbers; the result is their sum.

eg : _[k=1]

^[n] k³ = 1³ + 2³ + 3³ + ........ + n³

Here k varies from 1 to n and for each value of k. k³ is evaluated and these values are summed up to get the resultant sum.

basically differentiation is finding slope of a line or finding rate of change of something .summation means addition.
refer hc verma dor more explaination.
