Explanation

Extrapolation is the process of estimating a value outside the range of known data points.

In contrast, interpolation refers to estimating a value within the known range.

Explanation

- f tan xdx = ln[cos x] + C.

This is a standard result from integral calculus involving trigonometric functions.

Explanation

A small standard deviation means the data is tightly clustered around the mean.

This results in a less spread out (narrower) normal distribution curve.

Explanation

The turns ratio of a transformer is given by:

n = N₂ / N₁ = V₂ / V₁

Where:

- n is the turns ratio

- N₁ and N₂ are the number of turns in the primary and secondary coils

- V₁ and V₂ are the primary and secondary voltages

Given n = 5:

V₂ / V₁ = 5

This means the secondary voltage is greater than the primary voltage by a factor of 5.

Explanation

Regression is a defense mechanism where a person reverts to earlier behaviors or emotional states in response to stress or anxiety.

Recalling traumatic events like crashes may trigger such a regression to a more childlike state of coping.

Explanation

The phrase "came off" means something got detached or separated from its place.

Correct sentence: The handle of my bicycle suddenly came off. It is in my hands now.

Explanation

The discovery method encourages students to investigate, explore, and find information on their own.

It promotes deep understanding and active engagement with the content.

Explanation

A critical point occurs where the derivative of a function is zero or does not exist.

These points are important for finding local maxima, minima, or points of inflection.

Explanation

Tremble means غیر ارادی طور پر ہلانا

Shake means غیر ارادی طور پر ہلانا

Explanation

A switch operates at the Data Link Layer (Layer 2) of the OSI model.

It uses MAC addresses to forward data frames within a local network.
