3. Write the differential equation xy + y² = 0 in differential form. E. Write the differential equation (y)2 - 5y + 6 = (x+y)(y-2) in standard form.
The differential equation x · y' + y² = 0 in differential form is x · dy + y² · dx = 0.
The standard form of the differential equation (y')² - 5 · (y') + 6 = (x + y) · (y' - 2) is the equation y' - y - 3 = x.
How to analyze ordinary differential equations
In the first part of this problem we have a nonlinear diferential equation of the form f(x, y, y') = 0, which has to be changed into diferential form, defined below:
M(x, y) dx + N(x, y) dy = 0, where y' = dy / dx. (1)
Now we proceed to work on the ordinary differential equation:
x · y' + y² = 0
x · y' = - y²
x · (dy / dx) = - y²
x · dy = - y² · dx
x · dy + y² · dx = 0
The differential equation x · y' + y² = 0 in differential form is x · dy + y² · dx = 0.
The second part of the problem involves another nonlinear differential equation, of which we must find its standard form, also defined below:
f(y', y) = g(x) (2)
Finally, we proceed to modify the equation:
(y')² - 5 · (y') + 6 = (x + y) · (y' - 2)
(y' - 3) · (y' - 2) = (x + y) · (y' - 2)
y' - 3 = x + y
y' - y - 3 = x
The standard form of the differential equation (y')² - 5 · (y') + 6 = (x + y) · (y' - 2) is the equation y' - y - 3 = x.
RemarkThe statement presents typing mistakes, correct form is shown below:
3. Write the differential equation x · y' + y² = 0 in differential form. Write the differential equation (y')² - 5 · y' + 6 = (x + y) · (y' - 2).

During welding in the vertical position, the torch angle can be varied to control sagging.
a. true
b. false
Answer:
A: True
Explanation:
The given statement is true.
During welding in the vertical position, the torch angle is not typically varied to control sagging. This statement is False.
Sagging, also known as downward distortion, occurs when the molten metal in the weld pool pulls downward due to gravity.
To control sagging, the primary method is to adjust the welding parameters, such as the welding current, travel speed, and electrode angle, rather than the torch angle.
Maintaining a proper travel speed and using appropriate welding techniques, such as weaving, can also help to manage sagging.
Ensuring proper joint preparation and fit-up, as well as using suitable welding procedures, are crucial in minimizing sagging and achieving high-quality vertical welds.

Before a flight, especially for IFR (Instrument Flight Rules) operations, it's crucial to conduct a thorough pre-flight check of the vacuum-driven heading indicator, also known as the directional gyro or DG.
The heading indicator is a crucial instrument for maintaining proper heading during flight. Here are the key checks to perform:
- Power and Vacuum Source:
Ensure that the aircraft's vacuum system is functioning correctly and providing adequate suction to power the heading indicator.
Verify that the vacuum system pressure is within the manufacturer's specified range.
- Instrument and Case Inspection:
Visually inspect the heading indicator and its case for any signs of damage, cracks, or loose fittings.
Make sure the instrument's glass is clean and clear for easy readability.
- Zero Setting:
Set the heading indicator to the correct heading using the aircraft's magnetic compass or another reliable heading reference. This process is known as "synchronizing" the heading indicator.
- Gyro Drift Check:
- Operation Check:
