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

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.

Tremble means غیر ارادی طور پر ہلانا

Shake means غیر ارادی طور پر ہلانا

Explanation

Glass is an insulator because it does not allow electricity to pass through easily.

Silver, copper, and aluminum are conductors, meaning they allow electric current to flow.

Explanation

Force is defined as the rate of change of linear momentum with respect to time.

According to Newton’s second law, force causes a change in an object’s momentum.

Explanation

The given solution is already solved:

5x + 8 = 23

5x = 23 - 8

5x = 15

x = 15/5

x = 3

Explanation

F ∝ m1m2

If both masses are doubled, F' ∝ (2m1)(2m2) = 4m1m2

So, F' is 4 times F.
