Question

*when* do i use dot product in vectors?

Answer 1

what do u mean?

Answer 2

what kind of questions do I use dot product?

Answer 3

for example..what's the scenario that will tell me that i have to use dot product

Answer 4

angle between two vectors?

Answer 5

work done= F . ds

Answer 6

when two vectors are multiplied there reslut will be scalar then we can use dot/scalar product.

Answer 7

i didn't mean physics application...

Answer 8

do you know what is scalar?

Answer 9

you mean in maths?

Answer 10

actually....whenever u have to find a component of a vector along the other vector then we use dot product

Answer 11

ahh wait..i think i ahve a hypothesis

if two vectors are given and i need the angle between them...then i use the dot product

if the x and y components are given...i use arctan


is that right?

Answer 12

yeah.....
