    Partial Derivatives of x^2-y^2+2mn+15=0

    @jedishrfu please ignore my solution.try to draft your own solution.. the real question is x^2 - y^2 +2mn +15 =0 x + 2xy - m^2 + n^2 -10 =0 The Question is: Show that del m/ del x = [m(1+2y) -2 x n ] / 2 (m^2 +n^2) del m / del y = [x m+ n y] / (m^2 +n^2) note that del= partial derivatives...

    Graduate Where Can Adams-Bashforth-Moulton Method be Applied in Real-World Sciences?

    Thank you! I am trying to find the real application and use it to the program that i just created. I hope you guys could show me good example of the application of Adam Bashforth in other fields (Such as Engineering, Chemistry, Medical).

    Graduate Where Can Adams-Bashforth-Moulton Method be Applied in Real-World Sciences?

    No.. i just want to know the application. Adams bashforth somehow may have applications in other branch of science

    How many ways can a security code be formed with restrictions?

    supposely letter has 5P3 and numbers has 6P4 but as a whole i don't know how to compute it

    How many ways can a security code be formed with restrictions?

    You mean 5C3 x6C4?
  14. I

    How many ways can a security code be formed with restrictions?

    why i can't use 5P3 x 6P4? you mean i should use C?

    How many ways can a security code be formed with restrictions?

    Homework Statement A security code is formed by using three alphabet and four digits chosen from alphabet {a,b,c,d,e} and digits {1,2,3,4,5,6}. All digits and alphabets can only be used once. Find the number of different ways the security code can be formed if (a) there is no restriction...
