عندي عدة اسئلة عن التكاملات
وعلي فيها اختبار بكره العصر .. ممكن ـآحد يساعدني في حلهـــآ .!.
.
هذي هي الاسئلة __
Each DE in problems 15-20 is a bernoulli equation .
In problems 15-20 solve the given differintial equation by using an appropriate substitution
15) x dx/dy+y=1/y^2
16) dy/dx-y=e^x.y^2
17) dy/dx=y(xy^3-1
18 ) x dy/dx-(1+x)y
__________________________________________
In problems 27 verify that the given functions form a fundamental set of solutions of the differential equation on the indicated interval . form the general solution .
x^2.y''-6xy'+12y=0; x^3,x^4
(0 , الى مالانهاية )
