I think this integral calculation in Mathematica is wrong. I am quite sure, that Mathematica works ok, while I do not understand something. Please help me. Graphs (the red one is under the blue and the green): Wolfram Mathematica Symbolab: Last edited by skipjack; November 10th, 2017 at 05:02 PM.

Why do you think it's wrong? It's a decaying exponential.

How many decimal places are you allowing for the answer? $\int_{10.3}^\infty e^{39.1(x 10.3}dx$ $\frac{1}{39.1}\left[e^{39.1(x 10.3)}\right]_{10.3}^\infty$ $\frac{1}{39.1}\left(0 1\right)= \frac{1}{39.1}= 0.02557$
