Question

Which is the direction angle for v=-4i-j

Answer 1

The direction angle of the vector is 14 degrees

How to find the direction angle

To find direction angle, we use the trigonometric tan

The solution is as follows

let the angle be z, for v = -4i - j

x = -4,

y = -1

tan z = (y/x)

tan z = (-1/-4)

tan z = (1/4)

z = arctan (14)

z = 14.036
