Find the scalar and vector projections of b onto a. a=[1,2], b=[-4,1]

VladimirAG [237]

Answer

we have,

a=[1,2], b=[-4,1]

we need to find projection of b onto a.

scalar projection

= $\dfrac{a.b}{|a|}$

= $\dfrac{(1,2).(-4,1)}{\sqrt{1^2+2^2}}$

= $\dfrac{1\times (-4)+2\times 1}{\sqrt{1^2+2^2}}$

= $\dfrac{-2}{\sqrt{5}}$

now, vector projection

= $\dfrac{a.b}{|a|^2}.a$

= $\dfrac{(1,2).(-4,1)}{(\sqrt{1^2+2^2})^2}.(1,2)$

= $\dfrac{1\times (-4)+2\times 1}{5}.(1,2)$

= $\dfrac{-2}{5}.(1,2)$

= $(\dfrac{-2}{5},\dfrac{-4}{5})$
