Question

how do you find magnitude?

Answer 1

of which?

Answer 2

a vector?

Answer 3

i think it is of two vectors.. im not sure

Answer 4

if a,b are two vectors and angle between them is x then the magnitude's square is a^2+b^2+2ab cos x

Answer 5

ohh ok thanks

Answer 6

or if you're just given one vector let's say {a,b,c} then to find the magnitude of the vector then magnitude = \[\sqrt{(a^2 + b^2 +c^2)}\]

Answer 7

this is possible only when the vectors are mutually perpendicular

Answer 8

thank you

Answer 9

remember we were finding maginture of like -3
and it was 3
then the magintude of a is |a|
|a|=sqrt(a^2)
what about we went from (x1,y1) and (x2,y2)
it was sqrt{(x1-x2)^2+(y1-y2)^2)

Answer 10

for any inclined angle between them u have to add a cos x term. when the angle is 90 then the cos term vanishes nd u get a result like sqrt(a^2+b^2)

Answer 11

myininaya....u gave the distance between two vectors not the magnitude of the resultant...
