Question

Geometrical interpretation of second order differential equation

Answer 1

Answer:

Step-by-step explanation:

Recall from Calculus that the geometric meaning of the derivative at the point x0 is the tangent of the angle at which the tangent line at x0 intersects the x axis. ... Indeed, at each point the slope of this curve y′(x) is given by construction as f(x, y), which exactly means that this function solves ODE.

Answer 2

Step-by-step explanation:

To calculate the standard deviation for a sample of N measurements:

Sum all the measurements and divide by N to get the average, or mean.

Now, subtract this average from each of the N measurements to obtain N "deviations".

Square each of these N deviations and add them all up.

Divide this result by. (N − 1)
