And in the J, it is 17 times the sign of 243 again all centimeters. So therefore, Fergie, we know that in the eye direction equals 17 times the co sign of 243. Therefore, that gives us that the angle from Thebes positive X axis Going that way would be 243 degrees. That would be like starting at 2 70 and subtracting 27 degrees. Now, if we draw this one out, we can see that starting at the negative y axis, which would be right here. However, the direction of G is 27 degrees clockwise from the negative y axis.

And this is both in centimeters now, for G again has a magnitude of 17 centimeters.

So 17 times co sign and that would add to 117 17 times the sign of 117 in the J direction, and this is again in centimeters, so F equals negative, 7.72 in the eye, plus 15.1 in the J. For example, vector v (1,3) is not a unit vector, because its magnitude is not equal to 1, i.e., v (1 2 +3 2 ) 1. A vector that has a magnitude of 1 is a unit vector. Therefore, that would be your angle for both the coast for the I and J. A vector is a quantity that has both magnitude, as well as direction. That means starting at 90 degrees, you move another 27 so therefore the angler would be at would be the co sign of 27 plus 90 degrees. However, the direction is 27 degrees counterclockwise from the positive y axis. We know it's still the magnitude of 17 centimeters. And when you plug that into your calculator, we get that e equals 15.1 in the eye, plus 7.72 in the J in centimeters. Therefore, we know for the I direction is 17 times the co sign of 27 degrees in the eye, and it's J direction would be 17 times the sign of 27 degrees J on centimeters. E has a magnitude of 17 centimeters, and is that a direction counterclockwise from the positive X axis of at 27 degrees. This problem gives us the magnitude and direction of the vector and s asks us to find the components of that vector for the 1st 1 were given.
