    Can a rectangular component of a vector be greater than the vector itself?

    Answer:

                    No. The rectangular component of a vector can't be greater than the vector itself because the rectangular components of a vector \[\overset{\to }{\mathop{\text{A}}}\,\] are \[{{A}_{x}}=A\cos \text{ }\!\!\theta\!\!\text{ }\] and \[{{A}_{y}}=A\sin \text{ }\!\!\theta\!\!\text{ }\]. As \[\sin \text{ }\!\!\theta\!\!\text{ }\] and \[\cos \text{ }\!\!\theta\!\!\text{ }\] both are \[\le 1\], therefore \[{{A}_{x}}\]and \[{{A}_{y}}\] cannot be greater than A.
