The Ans. is 1, but i couldn't reach it .I'm gettin plenty of e-s.Pls help

U sre really sayin that a complex no. is a point in an argand plane. But how can a+ib represent an angle? What does it mean... An angle doesn't have an imaginary part does it??? Pls expln further...

8....

And 10 for Preity

Yes it is...The syllabus i have says so...

Alright...I refrain from wisecracks b'coz i'm a big fan of Ronaldo's...

Allright wiseguy...;)
9.3/10...Looks very scientific...Thought they were twin stars at firs...

Excellent........

9/10... nice lookin guy...

S1-S2 will give only give eq. for one of the tangents...The one which passes thru the point of contact...Circles which touch have two more common tangents...one above the two and another below it...Tho i don't know how to find their eqs. Sorry ....

Danny's rite...Go to display properties and change the resolution. Or u'll find a control somewhere to rotate ur screen...(not joking)

@sboosy...Thanx ...didn't see ur reply when i posted mine.....

@allamraju...OK Thanx man...

and it's not Abraham...it's Abram..:P

@sboosy
Why the multiplication by three? Didn't get that part...Can u pls expln?

Let n be the number of drops...Then their total surface area is 4n $\Pi$ r2. And their total volume will 4/3*n $\Pi$ r3. The volume of the larger drop will also be the same...if its radius is R, we have.

4/3 $\Pi$ R3=n4/3 $\Pi$ r3. --> R³=nr³

The energy released by the decrease in the total surface area causes the rise in temperature.

Energy(E)=surface tension *decrease in area=t*(4n $\Pi$ r² -4 $\Pi$ R² )

Rise in temp=E/(4/3 $\Pi$ R³ $\rho$ *c)

Pls rate if satisfactory...

Cheerio

Trunks dudes is the coolest...and of course Goku has no match...
