Best ResponseYou've already chosen the best response.1Calculus Questions are easy to solve once you know the formulas :) integration is used in finding are of solids, figures, etc. differentiation can be used to find rate of change of a quantity. and both of these have many other applications.. if you have any specific question, you please ask :)

Best ResponseYou've already chosen the best response.1thats correct, now \[\int x^n dx=x^{n+1}/(n+1) \\ \int x^2dx=... ?\]

Best ResponseYou've already chosen the best response.1it will be x^3/3 , as n+1 =3 \[ \int\limits_{l/2}^{+l/2}(x^22rx+r^2)dx\\= \int\limits_{l/2}^{+l/2}x^2dx2r\int\limits_{l/2}^{+l/2}x dx+r^2\int\limits_{l/2}^{+l/2}1dx = \\ =[x^3/3]_{l/2}^{+l/2} 2r [x^2/2]_{l/2}^{+l/2}+r^2[x]_{l/2}^{+l/2}\] got this ?

Best ResponseYou've already chosen the best response.0why u hav taken 2r &r out?

hartnn

Best ResponseYou've already chosen the best response.1because when we are integrating with respect to x, 'r' will be constant and can be taken out of integration and differentiation..

Best ResponseYou've already chosen the best response.0how u will know that x is a constant? or any digit or letter is a constant?

Best ResponseYou've already chosen the best response.1do you see 'dx' in integration, ? means only 'x' is variable, all other letters are treated to be constant.

Best ResponseYou've already chosen the best response.0the letter attach to d like dx always only that letter r variable?

Best ResponseYou've already chosen the best response.1sorry, yes. only that letter is variable. so here r is constant, x is variable.

Best ResponseYou've already chosen the best response.1now l/2 is upper limit and l/2 is lower limit. \[[x^3/3]^{l/2}_{l/2}\] is solved by first putting x= upper limit  x= lower limit like this : (l/2)^3/3 (l/2)^3/3 got this first term ?

Best ResponseYou've already chosen the best response.1can you try for other 2 terms ?
