# 1465 A Degrees to and from Radians Calculator

Contents

Elementary and middle school students measure their angles in degrees. When they get to high school, they find out that sometimes we prefer to measure angles in radians. Of course, they also need to convert degrees to radians and to convert radians into degrees. Since I have students who rely on calculators but don’t have access to one during this pandemic, I designed a calculator in Desmos to convert Degrees to and from Radians. The calculator doesn’t work like magic, still requires you to think about what you are doing, and should prevent some of the common errors in doing such conversions.

### Factors of 1465:

• 1465 is a composite number.
• Prime factorization: 1465 = 5 × 293
