look im giving u da correct soln
im telling u textbook method
 f(x)dx =g(x)+c , then
 
 
now see
f-1(x)dx
we put x=f(t)
dx=f`(t).dt
f-1(x)dx
=
tf `(t)dt
use integration by parts
we get
=tf(t)- f(t)dt
  f(t)dx =g(t)+c
=tf(t)-g(t)+C
t=f-1(x)
so we get
xf-1(x)-g(f-1(x))+c
so (c) is correct
please check whether there has been any mistake in the question
if it is (a)
then there is no function of g(X) in it

the book TMH is for those who understand the basics
TMH is question solving book the theory theyt give is inadequate.
u should learn first the basics from NCERT,ML Khanna too is good l

u can use this site too
http://www.goiit.com/chapters/tutorial/maths/complex-numbers.htm
it covers basics well and i got a lot from it.!

look joy we have to use basics for such questions rather than equations!!
when we take case of slip down friction acts on opposite side i.e up
and when it skids up friction acts at downdard to the banking
------------------------------------------------------------------------------------
the road has been banked so
the angle
tan=v2/rg
v=10m/s r=20m g=10m/s2
from here we get
tan =1/2
-------------
Case 1:-slips down
direction of friction is opposite to motion
we take components of Normal reaction and friction forces along vertical and horizontal axis
N(cos+sin)=mg ----------1
N(sin-cos)=mv2/r-------2
divide eq 1 and 2
and calculate v
Case 2:-skids up
direction of friction is opposite to motion
we take components of Normal reaction and friction forces along vertical and horizontal axis
N(cos-sin)=mg ----------1
N(sin+cos)=mv2/r-------2
divide eq 1 and 2
and get v
 
 
hope it helps
!!

if u want good books in theory
then take Concise inorganic chemistry by J.D lee
and i also know a good small book recommended by experts for
beginners
they are
Language of chemistry and chemical equations by G.D tuli


for questions U may take TMH or arihant books for solving

many say that TMH are more concise and have less out of course questions.

hey shivamk
i want to tell u a very important
fact
f(x) and g(x) are two differenciable,continuous functions
then f(x) +g(x) is differenciable everywhere

and if f(x) and g(x) are two non differenciable functions (but at same place)
then f(x) +g(x) is differenciable
only when both non differencial elements oppose each other
i mean they cancel the bend in the graph!!!

use basics to be correct everytime
i.e left hand derevative=right hand derevative

yaar wid 230 u shd expect below 4000 4 sure
but NIT trichy is popular so it will be tough

who knows u may well make it!!

depends on which course u wanna take

well i have hrd frm my brother who studiesat AMITY that amity university does not need AICTE approval
but ya it needs UGC approval so that its students after doind Btech
can apply for GATE and other exams

UGC team will visit amity in coming days!!
who knows they may get it!!

im telling u a good way of solving such questions

we take v=(ucosQ) i + (usinQ-gt) j
i,j are unit vectors to x,y axis
Q is angle made with the ground
and the point from where the particle is thrown as origin
so the equation of the
inclined plane in 2-D is
y=(1/sqrt(3))x


we tale vector m=cos 30 i +sin 30 j
this is unit vector along plane
we know the angle at which it hits the plane

wetake dot product of v and m
v.m=|v||m|cosF

where F is the final angle at which it hits the plane
hope u get it!!

sorry for not typing the solution(it was too late night)
 
 just
putting sol in some time.
-------------------------------------------
a(a^2 - 3b^2) = 2 ;
b(3a^2 - b^2) = 11;
 
now as i had said put a=rsinQ
b=rcosQ
we get
r3SinQ(1-4cos2Q)=2-------1
r 3CosQ(3-4cos2Q)=11----------2
divide eq 1 and 2
tanQ(1-4cos2Q)=2/11(3-4cos2Q)
now gather terms of cos2Q
we get
(tanQ-6/11)=4cos2Q(tanQ-2/11)
sec2Q(tanQ-6/11)=4(tanQ-2/11)
put sec2Q=1+tan2Q
now put tanQ=t
we get the equation
11t3-6t2-33t+2=0
now put it like this
11t3-22t2+16t2-32t-t+2=0
11t2(t-2)+16t(t-2)-(t-2)=0
so t=2 is a factor
that means tanQ=2
sinQ=2/sqrt(5)    cosQ=1/sqrt(5)
using this we conclude that answer is 5
