a question plzzzz........

OpenStudy (anonymous):

number of solutions of \[y=e ^{x} and y=sinx\] is/are:

OpenStudy (anonymous):

smone?????????

OpenStudy (anonymous):

this can be solved only graphically

OpenStudy (anonymous):

THNK GOD U R BACK HW 2 DO IT

OpenStudy (anonymous):

haha..nyc..only by graphing it

OpenStudy (anonymous):

OH BUT DIS I saw in bits sample papr

OpenStudy (anonymous):

dont sweat on it..wher did u get this sample paper

OpenStudy (anonymous):

actualy i dontb think this has any positive solution

OpenStudy (anonymous):

options r 0,1,2,and infinite

OpenStudy (anonymous):

kis pagal ne banaya hai yeh

OpenStudy (anonymous):

i confirmed...as i told u there r no positive solutions to this ..but there r 3 negative solutions..impossible to find out without a graphing program

OpenStudy (anonymous):

believe if i catch hol of him i m going 2 blast him

OpenStudy (anonymous):

one negative solution..issko chhodo..irrelevant..it can nevb askd in objective exams..let alone in bits

OpenStudy (anonymous):

I think it has infinitely many solutions.

OpenStudy (anonymous):

yeah now u think of it i too think the same

OpenStudy (anonymous):

Oh wait.

OpenStudy (anonymous):

coz e^x tends to zero on the negative side and hence itll cut sin x infinite times

OpenStudy (anonymous):

yeah ur right anwar

OpenStudy (anonymous):

Exactly.

OpenStudy (anonymous):

pellet i messed up

OpenStudy (anonymous):

such a fool i am

OpenStudy (anonymous):

I don't think it has any positive solutions.

OpenStudy (anonymous):

neither do i

OpenStudy (anonymous):

coz the max of sin x is 1 at pi/2 but thats not satisfying e^x

OpenStudy (anonymous):

for +ve x

OpenStudy (anonymous):

How can you say that you are fool? >.<

OpenStudy (anonymous):

but sweetz is gone :(

OpenStudy (anonymous):

Haha

OpenStudy (anonymous):

cz i messed up

OpenStudy (anonymous):

We all mess up. In an exam last week, I made a mistake in integrating x. :(

OpenStudy (anonymous):

hahahaha....in the IIT entrance i didnt c d end corrections in a physics question..lost 4 marks...200 ranks

OpenStudy (anonymous):

These things happen to everybody :(. I hated myself though. My teacher put the biggest question mark I have ever seen :D

OpenStudy (anonymous):

yeah..bt theyre only a minor blip as time goes on

OpenStudy (anonymous):

Yeah.
