Radians are just half-turns, so we use turns either way. Some equations look better in turns and some in half-turns, but the math works fine either way. Instea

Radians are just half-turns, so we use turns either way. Some equations look better in turns and some in half-turns, but the math works fine either way.
Instead to decide which is better think of how a new student might learn this intuitively:
How far around is it? 2.5 turns.
This is so much clearer than 5.0 half-turns.
Turns a more clear. No one
- gspr 4y ago> Radians are just half-turns, so we use turns either way. What? This thread is full of weird statements, but this one is among the weirdest. In what way is a radian a half-turn?
- tsimionescu 4y agoNo, radians are pi * half-turns. For example, a 90 degree angle is a quarter-turn (1/4 turns) or pi/2 radians. It is most definitely not 1/2 radians. Equivalently, radians can be said to represent tau turns: 1/4 turns is tau/4 radians.
