find the measure of a negative coterminal with 7(pi)/10 radians
7π/10 - 2π = ?
To find the measure of a negative coterminal angle with an angle in radians, you need to subtract a full revolution (2π radians) from the given angle.
In this case, the given angle is 7π/10 radians.
To find the negative coterminal angle, we can subtract 2π from 7π/10:
Negative Coterminal Angle = 7π/10 - 2π = 7π/10 - 20π/10 = -13π/10
Therefore, the negative coterminal angle with 7π/10 radians is -13π/10 radians.
