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

jimthompson5910 (jim_thompson5910):

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

OpenStudy (anonymous):

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

exactly
