How to solve
Degrees and radians measure the same turn on different scales: 180° = π radians.
Steps
- Degrees → radians: multiply by π/180 and simplify the fraction.
- Radians → degrees: multiply by 180/π.
- Keep radian answers exact, in terms of pi.
Example
Convert 150° to radians.
- 150/180 = 5/6.
- So 150° = 5π/6.
Answer: 5pi/6
How to type answers
- Write radians like pi/3 or 5pi/6; degrees as a plain number
