Question

Find the magnitude and direction angle of v=6(cos80° i + sin80° j)

Answer 1

In the general form

v = r*(cos(theta)*i + sin(theta)*j)

The magnitude of the vector v, or the length of the vector v, is r units.

The angle of the vector (that it makes with the x axis) is theta

Answer 2

so the magnitude is 6 and the direction angle is 80?

Answer 3

exactly

Answer 4

thanks!
