(1+x^{2}+y^{2}+x^{2}y^{2}) ^{1/2} + xy dy/dx =0 how to solve dis diffrential equation!?! ..please ans asap!! :)

1. Solve diff eqn dy/dx + y cotx = x2 cotx + 2x2. Find distance of the point (-2 , 3 , -4 ) from the line x + 2/3 = 2y +3/4 = 3z + 4/5 m,easutres II to plane 4x + 12y - 3z +1 =0

how can we solve ; dy/dx=tan 2(x+y) or dy/dx=tan square (x+y)

number chart for maths fair

Solve (1+y^{2})dx = (tan^{-1}y - x)dy

if x=a(t+sint) , y=a(1-cost) , show that y''=1/a , at t=90deegre .(or) pi/2

Solve:

dy / dx = x^{2} e^{-3y} . given that y = 0 when x = 0

The answer given in the book is : e^{3y} = x^{3} + 1

dy/dx+xsin2y=x^{3}cos^{2}y

Solve the differential equation:

x dy/dx + y = x cosx + sinx

given that y(pie/2) =1.

form the differential equation of a family of circles touching y- axis at origin

dy/dx = 1 + x + y + xy

Answer given in the book is : log | 1 + y| = x + 1/2 x^{2} + C
