Agnishom, please explain me the problem of Post : 94 in a much easier way.
If tan(a-b) = 1 , sec(a+b) = 2/√ 3 ; find smallest (+ve) value of b.
Prove that (2√ 3+3)sinθ +(2√ 3)cosθ lies between -(2√ 3+√ 15) and (2√ 3+√ 15)
This is a point to be noted,Agnishom. What Bobbym told is quite Rational.
The Flood Limit of 1 min between 2 posts is really very irritating,I whole-heartedly admit it.
Happy Birthday,Alokananda. Wish u a very happy and prosperous life ahead.
O.k. Shivam.
If a=b cos(2π /3)=c cos(4π /3) , then find: ab+bc+ac.
I understood it.Thnx.Can I give u another sum plz?
Thank u vry mch,Bob. But I could'nt understand why cos(a+t) = -cos(a+t) need 2 b shown in the 3rd last step?
Hi Bobbym,plz show me this sum too.
Can u plz help me out with a sum?
If 3sinθ +4cosθ =5,then 4sinθ -3cosθ =?
Agnishom, Bob had done it finally. See it.
Thank u Bob.
I could'nt understand what did u do.
Plz explain it once more for me,will u?
Yes,I did that too Mr.Chattopadhyay.
Yes,I liked it.
Hello everybody!
yes bob,u can show them.i would like 2 know it.
thnx. can u plz help with this sum? if x+a is the hcf of x^2 + px +q and x^2 + lx + m,find the value of a.
actually my 1 GB net in dongle was finished.can u plz tell me the formula bob bundy was talking about?
hello bobym,how r u?talking 2 u after a long time.
can u plz tell me the formulae?
