Hello I am trying to solve this integral 25-9x^2-25y^2/9 dydx integrating from 0 to sqrt(9-9x^2/25) and the limits of the second integration are 0 to 5. I can find tutorials on how to find the definite double integral of a single variable, but not for two variables. Any clues?(adsbygoogle = window.adsbygoogle || []).push({});

edit: so far I have tried nint(nint(25-9x^2-25y^2/9,y,0,sqrt(9-9x^2/25)),x,0,5) to which I get too few arguments and int(int(25-9x^2-25y^2/9,y,0,sqrt(9-9x^2/25)),x,0,5) which also results in "too few arguments." Thanks in advance!
