Chapter 5: Problem 3

Solve the differential equation. $$ y^{\prime}=\frac{5 x}{y} $$

Short Answer

Expert verified
The solution to the differential equation is \(y = \sqrt{5x^2 + 2C}\).

Step by step solution

01

Rearrange the Equation

Start by separating the variables to different sides of the equation. The equation \(y' = \frac{5x}{y}\) can be rewritten as \(yy' = 5x\).
02

Integrate Both Sides

Now, integrate both sides of the equation with respect to x, which is the independent variable in this case. Doing this: \[ \int yy' dx = \int 5x dx \]. which simplifies to \[\frac{1}{2} y^2 = \frac{5}{2} x^2 + C \].
03

Complete the Solution

Lastly, solving for y gives the general solution of the differential equation. This requires taking the square root of both sides: \[y = \sqrt{5x^2 + 2C}\].

Use the integration capabilities of a graphing utility to approximate the volume of the solid generated by revolving the region bounded by the graphs of the equations about the \(x\) -axis. $$ y=2 \arctan (0.2 x), \quad y=0, \quad x=0, \quad x=5 $$

The area of the region bounded by the graphs of \(y=x^{3}\) and \(y=x\) cannot be found by the single integral \(\int_{-1}^{1}\left(x^{3}-x\right) d x\). Explain why this is so. Use symmetry to write a single integral that does represent the area.
