Which is the principal value of arctan (3.7)?
PLEASE HELPP CANT GET IT WRONG

1.42π rad

Step-by-step explanation:

Principal value are known to be the largest value that can be equivalent to the trigonometry expression given.

Given

θ = arctan (3.7)

θ = 74.9°

The principal value of the angle can be found in the 3rd quadrant.

In the third quadrant, the angle gotten will become 180° + 74.9°

= 254.9°

Converting to radians

Since πrad = 180°

x = 254.9°

180x = 254.9π

x = 254.9π/180

x = 1.42π rad

The principal value of the angle is 1.42π rad.

true? is that what you're asking or do you mean something else?
