Hi All,
I would like an answer checked that I have found for the following problem.
\( y = 5 \int^1_0 \frac{1}{1+x^2} dx \)
using
\( \int^1_0 f(x) dx = (b-a)[\frac{f(a)+f(b)}{2}] \)
\( 5*((1-0)*[\frac{{\frac{1}{1+0^2}+\frac{1}{1+1^2}}}{2}])\)
\(5*0.75 = 3.75\)
Have I solved this correctly?
I have tried to chack this in matlab with the code below but I am not getting this answer which now I am not sure which is incorrect.
X = 0:0.5:1;
Y = 5*(1./X.^2)
Z = trapz(X,Y)
Thanks for your time
