A two-dimensional rotation is applied to an object by :
a) Repositioning it along with a straight-line path
b) Repositioning it along with a circular path
c) Repositioning it along with an elliptical path
d) None of these
Positive values for the rotation angle θ defines:
a) Counterclockwise rotations about the endpoints
b) Counterclockwise translation about the pivot points
c) Counterclockwise rotations about the pivot points
d) Clockwise rotations about the pivot points
The original coordinates of the point in polar coordinates are :
a) 𝓍ˊ = 𝓇 cos(ϕ + θ) & 𝒴ˊ = 𝓇 cos(ϕ + θ)
b) 𝓍ˊ = 𝓇 cos(ϕ + θ) & 𝒴ˊ = 𝓇 sin(ϕ + θ)
c) 𝓍ˊ = 𝓇 cos(ϕ − θ) & 𝒴ˊ = 𝓇 cos(ϕ − θ)
d) 𝓍ˊ = 𝓇 cos(ϕ + θ) & 𝒴ˊ = 𝓇 cos(ϕ − θ)
-----------is the rigid body transformation.
a) Scaling
