A Scientific Calculator in Terms of Pi

# Scientific Calculator in Terms of Pi

A scientific calculator is five dollars. Can you do the math?

### Use

There are many brands of scientific calculators out there. Each brand operates a little differently. You will need to become familiar with the way your scientific calculator works. For example, when performing trigonometric calculations, some calculators need you to enter the degrees first before choosing the appropriate trig function. Other calculators need you to enter the trig function followed by the degrees. So, for the trig function sin (60), you could be entering either [6] [0] [sin] or [sin] [6] [0]. Also, if you are working with angles, make sure your scientific calculator is using the appropriate angle measurement - either degrees or radians. You will see a button for [DEG] or [RAD]. In some calculators, one or the other will be the secondary function of a button.

Just because you're using a scientific calculator does not mean that you won't have to do any work. You still need to know your math because you still need to isolate your variable by hand. You need to do this part by hand as it tells you in what order to input your numbers and which operations to use to find your answer. Looking at what you've done so far, you see that you need to multiply the 10 by pi first. Then you need to add this number to 4.32. Then you divide what you get by 3 to find your answer.

### Pi

“Most of us learn about Pi in geometry, but Pi has many other real-world applications and appears in places you might not expect it, such as spectrum analysis, global positioning calculations and wind gust prediction." said Dr. Karen Greenhaus, Casio’s resident education-tech expert. “Casio’s high-quality scientific and graphing calculators can help students explore Pi-related activities and exercises easily due to their range of functions for even the most difficult equations."

Revolutionary among graphing calculators, Casio’s PRIZM fx-CG10 is jam-packed with features that allow students to solve the most challenging Pi equations and enhance their understanding of mathematics, including the world’s first Picture Plot function. The Picture Plot function enables users to plot graphs over pictures of real-life scenes and offers a color LCD with a full textbook-style display. Additionally, the PRIZM includes a multitude of functions that leverage the color LCD in graphing objects like dotted lines, circles and bars, and grid lines. (Source: www.casio.com)
