Question

Answer all parts of this vector calculus problem please

(a) True or False: The only time || + || = |||| is when = 0. You must provide an
explanation to get credit! Hint: think geometrically (you can assume both vectors are
in R²)
(b) A line L passes through the plane x-2y+3z = 3 at the point (1, 2, 2) in a perpendicular
direction to the plane. Find an equation for the line L.
(c) Is it ever possible that u 7=ux ? Explain.

(d) Describe what the linear transformation determined by the matrix
A=

[18]
does to the square with vertices (0,0), (1,0), (0, 1) and (1,1).
(i.e. figure out what it does to each of the vertices, sketch the new vertices, determine
how the area of this new shape compare to the area of the square)
