Maam energy of this signal is -1/2a the last step is e^infinity/2a-1/2a after limits we are still left with -1/2a

[dinkarjha]

Zero*infinity is indeterminate form so we have to apply l hospital rule and by that the power comes is infinite

[amittak]

0*infinity is a undeterministic form mam. We have to apply here limit concept how can you write directly zero.

[varietyasianshow]

mum, its wrong !
the end result is +infinity
1-if we multiply, we get 1/2T * ( exp(2aT/2a) = (exp(2aT)/2aT) * 1/2
using hopitla low we get 2*a(exp(2at)/1) * 1/2, this results +infinity

[RaviChauhan-tteq]

There is error in calculation of the energy's last step.

[kewang]

e^(aT) increase faster than 1/(2T), it should not be zero.

[gideonsaina]

You can still argue that 0*infinity is infinity ma'am

[manishakumari-hkkg]

is e to the power infinity is infinity????
