Question

How about the derivitive of ((-722t^2)/((19t^2)^2)+(49e^-7t)-128sin(8t).. any help there

Answer 1

\[-e ^{-7}*(1024*e ^{7}*t ^{3}*\cos(8*t)-49*t ^{3}-4*e ^{7}/t ^{3}\]

Answer 2

is your professor insane. Those are some big numbers on top of an already complex derivative

Answer 3

i agree lol

Answer 4

though i think he just tried to derive it several times thats possibly why it got a little messy or...webassign tends to be evil like that
