please tell can leave this calculas for iit? i have no confidence over calculas . i get confuse how to find the proper range......i am not  sure of algebra also????

please tell me the weightage of it in iit?

if i done 3-D, co-ordinate, differentiation, vectors, quadratic, binomial, sequence & series........ can i get good %age to clear maths paper in iit?

please pass this question to experts coz  am out of nickel please help..........xam is getting nearer????????

 

pleaseeeeeeeeeeee

1.check its countiunity

f(x)=[x]+(x-[x])^1/2

2. number of points in (1,2)  where function is discountinous f(x)=[2x^3 - 5]

3. function is differentiable or not f(x)= (x^2-1)lx^2-3x+2l+cos(lxl)

i am not able to to find domain or countiunity & diff of greatest integer especially. [(2)^1/2 sinx] sinx is n't is in under root. discuss its (i)countinuity at x=npi/2+pi/4

(ii)differentiablity at x=npi

(iii) maximum value at [-2pi,2pi]

am not also able to draw graph properly coz it makes easier . please me there too. also please help me how to about bijectin,surjective ,etc functions with graphs.

WHAT IS THE FULLFORM OF S.C.R.A?

WHEN IS THE PAPER HELD?

WHO ARE QUALIFIED?

PLEASE TELL THE WHOLE INFO................
