The  trigonometry angle range -π ≤ α ≤ π in radians means angle α is

  • between -π radians and π radians or  
  • -180° and 180°.

To answer the question, we need to know what a trigonometric angle range is

What is a trigonometric angle range?

A trigonometric angle range is the range of values which the trigonometric angle can have

Since we need to find the meaning of the  trigonometry angle range -π ≤ α ≤π.

We know that

  • -π radians = -π × 180°/π = -180° and
  • π radians = π × 180°/π = 180°.

Since α is in the range -π ≤ α ≤ π = -180° ≤ α ≤ 180°, this implies that the angle α is

  • between -π radians and π radians or
  • between -180° and 180°.

So, the  trigonometry angle range -π ≤ α ≤ π in radians means that angle α is

  • between -π radians and π radians or
  • between -180° and 180°.
