The Vector Components (3D) calculator computes the components of a vector in three dimensions (3D).
INSTRUCTIONS: Enter the following:
- (→F) Vector F
Vector Components: The calculator returns the following:
- |→F| - Magnitude of Vector (Note: Units will be the same as input vector)
- ˆF - Unit Vector
- (ρ,θ,φ) Spherical Coordinates with θ and φ in degrees (θ°,φ°)
- (r,Θ,z) Cylindrical Coordinates with θ in degrees (θ°)
- α - Angle between →F and x axis
- φ - Angle between →F and y axis
- θ - Angle between →F and z axis
The Math / Science
To compute the angle between the vector and axes, the unit vector is computed.
ˆF = →F|→F|
Then compute the dot products between the unit vector ˆF and the unit vectors for the axes (1,0,0) for x, (0,1,0) for y and (0,0,1) for z. The arccosine of each dot product is the angle between them in radians.
-
α = acos( ˆF⋅1,0,0)
-
φ = acos( ˆF⋅0,1,0)
-
θ = acos( ˆF⋅0,0,1)
