In your previous post, you have been asked what R3 stands for, and you have not clarified. We do not know yet if 3 is a superscript, a subscript, or just a number written in the wrong place.
Yes, φ equals a vector
< -sinφ, cosφ, 0 >.
Also, are
R,φ and z constants?
How is k related to z, there must exist a multiplicative constant, unless the constant equals 1.
Can someone help me with this please.
A vector field in cylindrical polar co-ordinates is given by
V = R Rˆ + R 3 s i n ( φ ) c o s ( φ ) φˆ + 3 z kˆ
where Rˆ, φˆ, kˆ are the appropriate unit vectors. Translate this vector field into the
Cartesian x, y, z co-ordinate system.
What is the first step??
Could you please guide me through the steps.
Thanks.
I get that
x = r cosφ
y = r sinφ
z = z
And i know i need to sub 'unit R^' with cosφ i + sinφ j and z with 'unit K^' with z k.
How about 'unit φ^' ?
What do i need to sub phi with?
I look else where it says sub it with -sinφ i + cosφ j.
But how? and why?
Can someone explain it to me?
Thanks alot!

Take a look at your previous post. See whether my solution makes any sense, and whether I interpreted things correctly.
