Projection onto polar basis vectors The point P has coordinates x = 5 m and y =-9 m relative to the origin O.
the vector v is v = 5i - 2j m/s
Matlab/Mathematica input: x = 5; y = -9; v = [5-2]; What is the orthogonal projection of u onto the vector-=-Ep associated with the polar coordinates for point P ?
Proj(v, v) = ____ i + _____ j m/s
