let the equation of parabola is y=ax^2+bx+c..(1)now put the values of (x,y) in the expression...now u will get 3 equations of a,b&c...r8so u have 3 equation and 3 unknown r8.. frm here find the value of a,b and c and put in the eq. (1)and u will get the eq. of parabola u can bring it in form x^2=y

what is n.... its a gp series

@ anirban r u mad he has given cosecx-cosx...not cot x

integration pi/2 to 3pi/2 [2sinx]dx [ ] -> gratest integer function

the solution is:make the graph of [sinx]its zero in interval pi/2 to pi r8...so the area bounded is zeror8now see in the interval pi to 3pi/2 [sinx] is -1....r8now integrate itu get integration pi to 3pi/2 of -1...r8... finally the ans. u will get is -pi/2
