Solve the differential equation dy/dx= y^2/x^3 for y=f(x) with the condition y(1) = 1.
Gennadij [26K]
We will use seperation of variables

tmes both sies by 1/(y^2)
times both sides by dx

we get

1/(y^2)dy=1/(x^3)dx
integrate both sides
-1/y=1/(2x^2)+c

initial condition, (1,1)
-1/1=1/(2(1^2))+c
-1=1/2+c
-3/2=c


-1/y=1/(2x^2)-3/2
solve for y
-1=y(1/(2x^2)-3/2)
y=-1/(1/2x^2-3/2)
y= \frac{2x^2}{3x^2-1}

Find y when x=9 if y varies directly as x, and y=245 when x=7
Aleonysh [2.5K]
Since y varies directly as x, you know that y=245 and x=7 can be used as a proportion, 245/7.  When you multiply this proportion to 9, you get 315.  This is the value of y when x=9.  

y=315

3 3/4 / 2/5 = what? I'm struggling
Soloha48 [4]

Lets convert 3 3/4 into improper fraction first.

3\frac{3}{4}  =  \frac{3 \times 4 + 3}{4}  \\  =  \frac{15}{4}

\frac{3\frac{3}{4} }{ \frac{2}{5} }  \\  =  \frac{15}{4}  \div  \frac{2}{5} \\  =  \frac{15}{4}   \times  \frac{5}{2}  \\  =  \frac{75}{6}  \\  =  \frac{25}{2}  \: or12  \frac{1}{2} or \: 12.5
