Double Integral of rSinx dr dx form 0 to π and 0 to aCosx | Double Integral in polar function

Show that f(x,y) = xy/√(x2+y2) is continuous at origin when f(0,0)=0

Double limit exist but repeated limits do not exist at origin for , f(x,y)=xSin(1/y)+ySin(1/x)

f(x,y)= (x2-y2) /(x2+y2) Show that the repeated limit exist and are unequal but the double limit .

Define simultaneous limit and prove that double limit of (2xy)/(X2+y2) does not exist at (0,0)

Solve (x2-y2)pq-xy(p2-p2)-1=0 by charpit's method PDE

Solve p2+q2-2px-2qy+1=0 by charpit's method .p^2+q^2-2px-2py+1=0

solve px+qy=pq by charpit's method.

Working rule for charpit's method of partial differential equation. px+qy=pq.
