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):

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

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
