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
<h3>What is a trigonometric angle range?</h3>
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°.
