Explanation

In Newton's divided difference interpolation method, the independent variables are at unequal intervals.

Thus, in this method, the variation in function f(x) and the variation in x are considered

Explanation

The equation of the type $y = x frac{dy}{dx} + f frac{dy}{dx}$  can be identified by comparing it to the differential equation form:

$y = x frac{d^2y}{dx^2} + f frac{dy}{dx}$

In this form, the equation involves both the second derivative $frac{d^2y}{dx^2}$ and the first derivative $frac{dy}{dx}$ with coefficients $x$ and $f$ respectively.

Therefore, among the options provided, the equation that fits this type is:

$y = x frac{d^2y}{dx^2} + f frac{dy}{dx}$

This equation indicates a relationship where $y$ is expressed as a combination involving both $frac{d^2y}{dx^2}$ and $frac{dy}{dx}$, with coefficients $x$ and $f$ respectively.

Explanation

The absolute error is defined as the absolute difference between the actual value and the estimated value.

It is given by ∣a−e∣, where a is the actual value and e is the estimated value. 

Explanation

In the sentence, "Until he came to the United States, he didn't know how to cook,"

the use of "didn't know" correctly matches the past simple tense for the negative form, 

And "How to cook" is the appropriate phrase to describe the lack of knowledge. 

Explanation

The phrase "used to" is correctly followed by the base form of the verb.

It indicates a habitual action in the past that is no longer true.
