Use mathematical induction to prove that if L is a linear transformation from V to W, then L (α1v1 + α2v2 +· · ·+αnvn)= α1L (v1)
e-lub [12.9K]

Answer:

The proof is shown in the explanation below.

Step-by-step explanation:

Analysis:

The proof by induction focuses on n. In this case, let n = 1, and L^{1} will be a linear operator since L^{1} = L

The exercise will show that L^{n} is a linear operator on V and that L^{n+1} is also a linear operator on V. This, follows that:

L^{n+1} (av) = L(L^{m}(v_{1}+v_{2})\\                   = L(L^{m} (v_{1} + L^{m}v_{2})\\                   = L(L^{m}v_{1} + L(L^{m}v_{2})\\                   = L^{m+1}(v_{1}) + L^{m+1}(v_{2})

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parab
salantis [7]

I would not normally stop to answer this question, mainly because
there is no question asked.  It's just three statements.

I do have to stop here and leave a remark, however. 

Math and Physics are closely enough related that I would not
have expected to see what I see here.  Although the math in
this question is reasonable, the Physics is inexcusable.

A rainbow is always a part of a circle.
Rainbows are never parabolas.

You could never cut a parabola out of paper, and then
hold it up in front of you after a rainstorm, and match it
to the rainbow.
