Question

formula to find the direction of vector

Answer 1

Answer:

The direction of a vector is the measure of the angle it makes with a horizontal line . tanθ=y2 − y1x2 − x1 , where (x1,y1) is the initial point and (x2,y2) is the terminal point.

formula to find the direction of vector

$\mathfrak{\huge{\red{\underline{\underline{Answer :}}}}}$

$:\implies\sf$Vector are those quantity which has both magnitude and direction.For example: Velocity, Displacement, force,weight etc.

$:\implies\sf$ As we know that the angles made by

the the revolving line may be positive or negative according to the revolving line revolves in anticlockwise are clockwise direction.If the line revolves in anti-clockwise direction,then the angle made by the line with the x-axis is positive and negative angle if the line rivers in clockwise direction.

The Formula For calculating The direction of vector is :-

$\: \: \: \: \: \: \: \: \implies{\underline{\boxed{\sf{ \tan = \frac{y \: component}{x \: component} }}}}$
