how to change the code to make work the solution for this integral

can you help me solve this integral with simpson ?

Please post an image of the integral, or use latex to post it. The character after the integral but before the z is unreadable. Is z being multiplied by negative 2 or is it z raised to the -2 power ?

Your units look strange.

Is it clear now ?

[Xhenis Bordulla]

-----> z is in the (-2) power

R = 3960 and g = 0.00609

[Walter Roberson]

The integral itself has a value of 1, so v^2 = 2*g*R .

[Xhenis Bordulla]

Why is it 1 ?

[Walter Roberson]

>> syms a b z positive

>> int(z^-2,z,a,b)

ans =

1/a - 1/b

And in the limit, 1/infinity is 0, so you get 1 divided by the starting value as the result.

Consider that diff(z^-1,z) is -1*z^-2 so integral of z^-2 is -z^-1

Okay thanks a lot,,, i ill try this one
