Explain why arctan(1) = 45° or π/4.

xeze [42]

Answer:

<em>Explanation below</em>

Step-by-step explanation:

<u>Inverse Trigonometric Functions</u>

They are defined as the inverse of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant.

The corresponding inverse functions are called arcsin, arccos, arctan, arccot, arcsec, arccsc.

These inverse functions in trigonometry are used to get the angle with any of the trigonometry ratios.

For example,

$\displayystyle \sin 30^\circ=\frac{1}{2}$

Then:

$\displaystyle arcsin \frac{1}{2}=30^\circ$

Since:

$\tan 45^\circ=1$

Or, equivalently:

$\displaystyle \tan \frac{\pi}{4}=1$

Then:

$\displaystyle arctan(1)=45^\circ$

Or:

$\displaystyle arctan(1)=\frac{\pi}{4}$

Over 7 months, the weight of a baby measured in pounds doubled. Does its weight measured in kilograms also doubled

Maksim231197 [3]

Answer:

Yes

Step-by-step explanation:

Yes. Explanations vary. Sample explanation: The weight itself doubles, so

any measurement of the weight using the same units will also double. We

can also see that by saying if the weight is x pounds, then double that weight

would be 2x pounds. The weight in kilograms will be x ÷ 2.2, and the double

weight will be or (2x) ÷ 2.2 2(x ÷ 2.2), which is also double.
