The following cryptogram was encoded with a

Verified answer TRIGONOMETRY The famous formula

e^{a+b i}=e^{a}(\cos b+i \sin b)

e a+bi =e a

(cosb+isinb) is called Euler’s Formula, after the Swiss mathematician Leonhard Euler (1707–1783). This formula gives rise to the equation

e^{\pi i}+1=0 e πi

+1=0 This equation relates the five most famous numbers in mathematics—

0,1, \pi, e

0,1,π,e, and i—in a single equation. Show how Euler’s Formula can be used to derive this equation. Write a short paragraph summarizing your work.

The table shows the temperatures T (in degrees Fahrenheit) at which water boils at selected pressures p (in pounds per square inch).

\begin{matrix} \text{Pressure, p} & \text{Temperature, T}\\ \text{5} & \ {162.24^{\circ}}\\ \text{10} & \ {193.21^{\circ}}\\ \text{14.696 (1 atm)} & \ {212.00^{\circ}}\\ \text{20} & \ {227.96^{\circ}}\\ \text{30} & \ {250.33^{\circ}}\\ \text{40} & \ {267.25^{\circ}}\\ \text{60} & \ {292.71^{\circ}}\\ \text{80} & \ {312.03^{\circ}}\\ \text{100} & \ {327.81^{\circ}}\\ \end{matrix}

## THIS USER ASKED

**Which expression can be used to determine the reference angle for an angle, x, measuring 150°? 180° – % %-180″ 380′ – X-380**

## THIS IS THE BEST ANSWER

180 ° -x

Step by step explanation:

The reference angle is the smallest positive angle between the terminal radius and the x-axis. For a 2-Square angle such as 150 °, the reference angle is …

180 ° -x

If your choice of answers is actually 180 ‘-x, then the correct answer is “none of the above.” It is 180 ‘3 °, since it is 60 minutes in phase.
