Differential Equations: (3y - 2yx^2)[ 1 + ln^2 (2x^3 / 3y^2) ] dx - 2x dy = 0
The topic is Additional Topics in Ordinary DE of the first order. Thank you so much.
3y-2yx^2 [ 1 + (ln (2x^3 / 3y^2))^2 ]dx - 2xdy =0
Differential Equations: Bernoulli's Equation $1 - 3rss' + r^2 s^2 s' = 0$
Bernoulli?
1- 3rss' + r^2 s^2 s' =0
Differential Equation: $ye^{xy} dx + xe^{xy} dy = 0$
Please help me to solve this differential equation
yexydx+xexydy=0
Differential Equations: $(r - 3s - 7) dr = (2r - 4s - 10) ds$
The topic is Additional Topics in Ordinary DE of the first order.
(r-3s-7)dr=(2r-4s-10)ds

Differential Equations: $(x - 2y - 1) dy = (2x - 4y - 5) dx$
Coefficient Linear in Two Variables? Help please.
(x-2y-1)dy=(2x-4y-5)dx
DIIFERENTIAL EQUATION: $(x^2 + y^2) dx + x (3x^2 - 5y^2) dy = 0$
( x^2 + y^2 ) dx + x (3x^2 - 5y^2 ) dy = 0
DE: $x \, dx + [ sin^2 (y/x) ](y \, dx - x \, dy) = 0$
xdx + sin^2 ( y/x ) [ ydx - xdy ] = 0
statics
determine the required length of the cord AC so that the 8 kg lamp is sudpended. The undeformed length of the spring AB is I' ab = 0.4m, and the spring has a stiffness of Kab = 300 N/m.
