I have the following as an input:
https://www.wolframalpha.com/input/?i=%282*c*N*%28m%2Bp%29%29%2F%28%28m%5E2%29*p%29+substitute+c+%3D+sqrt%28c%5E2+-+%28%284%2F3000%29*k*N*%281%2Bm%2Fp%29%29%5E2%29
If I right click on the result and open in a new link I get this:
https://www.wolframalpha.com/input/?i=%282+N+sqrt%28c%5E2+-+%28k%5E2+N%5E2+%281+%2B+m%2Fp%29%5E2%29%2F562500%29+%28m+%2B+p%29%29%2F%28m%5E2+p%29&assumption=%22ClashPrefs%22+-%3E+%7B%22Math%22%7D
Which is wrong.
If I explicitly add operators, ie k^2 * N^2 * (1 + m/p)^2, I get the correct answer.
Does anyone know what is going on here?
Ok I’ve worked it out.
Wolfram|Alpha clearly doesn’t like capital N as a variable, n is ok.
