Homework Statement
There is a problem in physics. i need to calculate the definite integral:
$$y=\int^{10}_2 \frac{13.2}{x^{1.4}}$$
Homework Equations
$$\int x^{a}=\frac{1}{a+1}x^{a+1}$$
The Attempt at a Solution
$$y=\int^{10}_2 \frac{13.2}{x^{1.4}}=13.2\int^{10}_2 x^{1.4}=13.2 \frac{1}{0.4}x^{0.4}^{10}_2=0.63$$
According to a graph i made with a graph software it came out 11.9, see picture
