Question 1

Which angle unit is most accurate?

Accepted Answer

All units are equally accurate; they're just different ways to express the same angle. Radians are preferred in mathematics.

Question 2

How many degrees is one radian?

Accepted Answer

One radian equals approximately 57.2958 degrees (180/π).

Question 3

What's the difference between degrees and radians?

Accepted Answer

Degrees divide a circle into 360 parts (historical, from Babylonians). Radians use the mathematical relationship where 2π radians = 360°, making calculus simpler.

Question 4

When should I use radians vs degrees?

Accepted Answer

Use degrees for everyday angles and navigation. Use radians for mathematics, physics, and programming where trigonometric functions expect radian input.
