1. IM very confused about the meaning of these cylindrical vectors
for Cartesian vectors if i say A = 1ax + 2ay + 3az
I know i mean a vector with a magntiude of 1 in the x direction 2 in the y direction and 3 in the z direction and i make a line from the origin to point (1,2,3).
Now for cylindrical I cannot think the same way
for a point i can make a point easily it seems to have a similar meaning (r is the magntiude from origin to the point, phi being the angle from x and z being the regular z)
now for a vector example a = 1 ap + 2 aphi + 3 az
Im very confused how do i draw this vector and what does it mean?
the magntiude along p is 1 so the angle is 2? from the x axis?
i don't think this is correct.. I can't understand this help!
