)dy/dx = y² and show that the solution represents a family of circles touching the y-axis at the origin.

2)A is a hemisphere which can be enclosed inside another hemisphere B when required both are provided with insulating handles. A is carries a charge on A completely to B?

3)Find the area in squ.units formed by y=cos x ,y=sin x,and x=0 in the first quardrant.

please do it.

Two parallel capacitor A and B having capacitance of 1 ?micro farad and 5 micro farad are charged separately to the same potential of 100 volt .Now positive plate of A is connected to the negative plate of B and the negative plate of A to the positive plate of B. Find the final charges on each capacitor and the loss of electrical energy in the capacitors.

A battery of 10 v is connected to capacitor of capacity 0.1 micro farad .The battery is now removed and this capacitor is connected to a second uncharged capacitor .If the distributes equally on these capacitors, find the total energy stored in the two capacitors. Further compare this energy with the initial energy stored in the capacitors.

Show that integral 0 to

/2sec²x /(secx+tanx)ⁿdx(n>1)=n/n²-1

Write down expressions for the capacity of the following

a) A spherical capacitor partly filled with a dielectric.

b)A spherical capacitor filled with a dielectric.

c) A cylindrical capacitor filled with a dielectric.Write down the meaning of the symbols

Electrostatic experiments do not work well during humid days.why?

A point positive charge is released at a point in a non uniform electric field. How will it move?

Let F(x) = f(x)+f(1/x) where f(x)= integral 1 to x ( log t)/1+t dt. Then prove that F(e)is equal to ½.

Show that integral 0 to

/2sec²x /(secx+tanx)ⁿdx(n>1)=n/n²-1

please do it

SIR,

Iam a plus one student in a local school.My syllabus is in a SCERT pattern.the problems you give in the home page i can't understand it. please help to follow your syllabus.Is any chance to get the iit to me?which books i want to reffer?

d)none of these

d)cot11

Is the IIT is a objective type exam?

how many mark for the IIT exam?

how i can prepare for the IIT exam?

please answer these questions.

sin5x-2sin3x+sinx/cos5x-cosx

prove that tan A/2. tanB/2.tanC/2+tanC/2. tanB/2=1?

Prove that cos^2A+cos^(A+120)+cos^2(A-120)=3/2?

Aball of mass m is projected with a speed u in to a barrel of spring gun of mass M,initially at on frictinless surface. the mass m sticks in the barrel at the point of maximum compressin of the spring. what fraction of the KE of the ball is stored in the spring? neglect friction.

please sent a model question paper of IIT .I have no coahing centre here.

please sent it to sreejithmsstudent@yahoo.com .
