सिद्ध कीजिए कि `v=(A)/(r)+B` अवकल समीकरण `(d^(2)v)/(dr^(2))+(2)/(r)(dv)/(dr)=0` का हल है।

Show that,v=(A)/(r)+B satisfies the differential equation (d^(2)v)/(dr^(2))+(2)/(r)*(dv)/(dr)=0

Show that , v = (A)/(r) + B satisfies the differential equation (d^(2) v)/(dr^(2)) + (2)/(r) .(dv)/(dr) = 0

सिद्ध कीजिए कि |vecA xx vecB|^(2) + |vecA * vecB|^(2) = (AB)^(2).

सिद्ध कीजिए कि 2tan^(-1)sqrt((b)/(a))=cos^(-1)((a-b)/(a+b))

int(2v^(2))/(v^(2)+v-2)backslash dv

(dv)/(r^(2))=4pidr, when r=0, v=0

Show that, v = A/r + B satisfies the differential equation (d^2v)/(dr^2)+2/r.(dv)/(dr)=0

Given : V=4/3pir^(3) , find (dV)/(dr) and hence (dV)/(dr)]_(r=2) .

If ^(28)C_(2r):^(24)C_(2r-4)=225:11,f in dr
