Question 2 The angle between vectors 2i+3j+k and 2i-j-k is ???? And

tell how to find an angle between vectorrs

#243 Re: Help Me ! » Equation » 2017-04-25 16:01:16

I solve In my copy it's ans same as question but it is wrong

#244 Re: Help Me ! » Distance » 2017-04-25 16:00:11

But if it' is negative such as Distance of point (-2,3) form y axis ???
So why ans is 2??? Why not negative

#245 Re: Help Me ! » Distance » 2017-04-25 15:17:42

ok but in my question can is use phytagoras??

distance of point 2,3 form yaxis

#246 Re: Help Me ! » Distance » 2017-04-25 13:45:10

It make right triangle only in this question ?? It is possible to use this formula in my question of Distance of point (2,3) form y axis ???

#247 Re: Help Me ! » Equation » 2017-04-25 13:42:27

Ok get the ans of question 1 but why we use slope intercept form??

#249 Re: Help Me ! » Distance » 2017-04-25 02:05:23

How to use phytagoras theorm in this question??

#250 Re: Help Me ! » Distance » 2017-04-25 02:02:54

We calculate by scale or other thing??or other method??
