Determine which of the following equations are separable. If it
is separable, find its general solution. Then, match one of the
differential equations to the slope field below and sketch the
solution curve corresponding to an initial condition of y(0) =
0.
(i) y0 = y−2x
(ii) dy dx = −2x(y−3)
(iii) y00 + 4y = 6cos(t)
(iv)dy/dx=1/ y
Only (ii) and (iv) is separable differential equation.
ii>
integrating both side:
ln(y-3) = x^2 + C, where C is integral constant.
x = 0, y = 0
0 = 3 +k
=> k = -3

iv>>
integrating both side:
for x = 0, y = 0 => C = 0
therefore ,
