यदि सदिश `bara` और `barb` परस्पर लंबवत हैं, तो सिद्ध कीजिए कि
`|bara+barb|^(2)=|bara|^(2)+|barb|^(2).`

[bara barb barc]+[bara barc barb] =

[[bara-barb, barb-bara, barc-bara]]=

bara.(barb+barc)xx(bara+barb+barc)=

The vectors bara,barb and bara+barb are

The vectors bara,barb and bara+barb are

If bara and barb are non-zero vectors such that abs(bara+barb)^(2) = absbara^(2) +absbarb^(2) , then find the angle between bara and barb

(bara+barb).(barb+barc)xx(bara+barb+barc)=

(bara+barb).(barb+barc)xx(bara+barb+barc)=

If absbara = 3,absbarb =2 and theta " is angle between " bara and barb , " then what is the value of " abs(bara+barb)^(2)+abs(bara-barb)^(2) ?
