Answer:
<em>The order of subtraction is not important in any of the coordinates</em>
Step-by-step explanation:
Distance Between Two Points
Given two points (x1,y2) (x2,y2), the distance between them is given by the formula
The difference between both coordinates is squared, then added, and finally extracted the square root.
Based on the principle that
and also
We can notice it doesn't matter the sign of a the square of a is always positive. If we had subtracted in the opposite way, the distance would have resulted in exactly the same. In other words, the above formula is exactly the same as
As seen, it applies for both coordinates
Answer:
Step-by-step explanation:
Rewrite the differential equation as:
Integrate both sides with respect to x:
Integrate one more time both sides with respect to x:
Now that we find the solution, let's find its derivate:
Evaluating the initial conditions:
Replacing the value of the constants that we found in the differential equation solution:
