Position vector in cylindrical coordinates
Were given a Cartesian vector defined as: V → = e ^ x + e ^ y + e ^ z, which is defined at point (1, 2, 1). I'm asked to find the components of this vector in the cylindrical and spherical systems. My first thought was to use r = x 2 + y 2, ϕ = t a n − 1 ( y / x), and z = z for the cylindrical part which would give me.A point P P at a time-varying position (r,θ,z) ( r, θ, z) has position vector ρ ρ →, velocity v = ˙ρ v → = ρ → ˙, and acceleration a = ¨ρ a → = ρ → ¨ given by the following expressions in cylindrical components. Position, velocity, and acceleration in cylindrical components #rvy‑epIn Cartesian coordinates, the unit vectors are constants. In spherical coordinates, the unit vectors depend on the position.
