i know that this integral would take pages upon pages to solve so i m askin anyone out to there to plug it into their maple or mathlab (since mathematica doesnt return any answer) and just post the answer... i really need it

$$\int_{\lambda=100}^{\lambda=1000} \frac{1}{\lambda^5 (e^{\frac{2.4*10^{-6}}{\lambda}} -1)}d \lambda$$
im not sure why mathematica doesnt yield any answer

Well, Maple gave me this: $$-2\cdot 10^{11}+9.95\cdot 10^{-13}i$$

Hehehe, I didn't think of using my calculator. And yes, it gives the same answer as yours, not the one Maple gave out. Strange.
