#1 Posted 10:09pm 11-03-10 Objective 11. If y= cosec x (cot[p]–1[/p]x) thendy/dx a. x/[sqrt]1-x[p]2[/p][/sqrt] b) -x/[sqrt]1+x[p]2[/p][/sqrt] c) x/[sqrt]1+x[p]2[/p][/sqrt] d) None 5. If A and B are such events that P(A) > 0 and P(B) ≠ 1 then P( [o]A[/o]/[o]B[/o] ) is equal to a) 1– P(A∪B)/P(B) b) P(A)/P(B) c)1-P(A)/P(B) d)1-P(B/A)

#2 Posted 10:39pm 11-03-10 Re: Objective 13....2 tan(x/2)-x....so D) will be right i think u can also refer this for the solution which i have referred[3]http://www.wolframalpha.com/input/?i=integration+(1-cos+x)/(1%2Bcos+x)dx[3][3]

#4 Posted 08:06am 12-03-10 Re: Objective 14 .I=∫2sin[p]2[/p](x/2)/2cos[p]2[/p](x/2)=∫tan[p]2[/p]x/2=∫sec[p]2[/p]x/2-1 |
