Title: How would you visually distinguish between scalar multiplication and a scalar multiplied by a vector? Post by: riverviewguit on Feb 12, 2013 I know you can multiply vectors by scalar multiplication, but how would you distinguish this, in terms of mathematical symbols, from multiplying a scalar by a vector (not scalar multiplication)--of which, the latter you can't mathematically do.
Title: How would you visually distinguish between scalar multiplication and a scalar multiplied by a vector? Post by: findingnemo41 on Feb 12, 2013 I don't understand what you're asking. Scalar multiplication on a vector involves a scalar multiplied by a vector. What do you mean by "multiplying a scalar by a vector (not scalar multiplication")? In what scenario would that not be scalar multiplication?
A scalar multiplied by a vector is a vector (on with a new magnitude, the old vector has been re-SCALed). Whereas, a scalar multiplied by a scalar produces another scalar. Maybe that's what you're thinking about? |
