Mathematics
1 answer:
BARSIC [14]4 years ago
4 0

Answer:

  No. The reciprocal of a function is rarely the same as the inverse of the function.

Step-by-step explanation:

tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.

tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.

The attached graph compares the two functions.

How do you find the median of these numbers $17.49, $11.29, $16.89, $11.79?
luda_lava [24]
Good morning, kid. It's quite easy.

The median is the middle number in a set after you place them least to greatest:

$11.29, $11.79, $16.89, $17.49

Well, since the numbers in the set are even, meaning there are only 4 numbers, we pick out the 2 middle numbers which would be, $11.79 and $16.89. Find the average (add them and divide by 2) and you'll get the median.

$11.79 + $16.89 = $28.68/2 = $14.34
Thus, the median is: $14.34
