Hey will u please explain?I already had the ans.

Do U Wanna say that IIT Delhi is worse than all these?ARE U NUT? I agree with coolyog this ranking is pure crap.

If frequency of oscillation of a body undergoing SHM is f,with what frequency does the K.E oscillates???

Three normals to parabola y^2=4x meet at (h,k). Prove that h>2

Well its something even divided by a multiple of three. Thus it wud be an irrational term with infinite digits.Well i think so.

Thanx

area=a^2-b^2-c^2+2bc

Dividing both sides by 2bc, you'll get

ar/2bc=1-cosA

now ar = 1/2bc sinA

Putting value

(sinA)/4=1-cosA

tanA=4/cosA - 4

Put cosA value using cosine rule to get ans

How do u solve such type of ques-

Find d number of rational terms in the expansion of

{2^(1/5) + 3^(1/10)}^45.Kindly explain

But its not the way u prove things.Can u prove taking a general tangent?

Thats right man, good. AND ITS MR.Sankalp

A tangent to ellipse x^2 + 4(y^2)=4 meets the ellipse x^2 + 2(y^2)=6 at points P & Q. Tangents at P & Q to the latter ellipse meet at point R.Calculate anglePRQ.Explain the solution

i make it seventy

What happened aspiring IITEEans, cant solve this prob or what?????

A detective was called to investigate a suicide or murder case. He broke open the locked door (it was bolted from inside) of the room in which the death had taken place. A guy's dead body was hanging from the ceiling fan by means of a rope. He somehow calculated that the death occured nearly 24 hours ago. There was no window or any other means of entering into the room except the door. Due to rain all night, the room's walls and cieling had water spots(seelan in hindi), there was also some water on the floor. The detective found a knife from the guy's pocket but it was clear that he was not stabbed.There was no furniture or any other object in the room.The detective ruled out that it was a suicide.But how did the guy commit suicide when his height was too less than height of cieling fan??????

Is anyone solving this prob? If yas then post a yes please.
