Consider the space defined by orthogonal unit vectors iand j. Let ai + bj be a vector in that space. Its direction is arctan(b/a) provided a � 0. If a � 0, the direction is pi/2 radians (or in the jdirection).
Angles are measured from the positive direction of the iaxis in the anticlockwise direction.

How do you find the magnitude and the direction of a vector?
Use trigonometry.
How do you find a vector if you have itsmagnitude and its direction given?
That's it! You know everything there is to know about it. It's not as if you have to wander through a crowd of vectors and find one that matches the description. "Find the vector" means figure out its magnitude and direction. If the problem already gave you the magnitude and direction, then it's unlikely that it's asking you to 'find' that same vector.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
What is the direction of the resulting vector if vector of 2 units North is added to a vector of 2 units South?

Can you graphically represent a vector which has magnitude but no direction?
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
How can you find a unit vector in the same direction as the given vector?
Divide the vector by it's length (magnitude).

Find a unit vector in the direction from 3 -1 4 to 1 3 5?
find the vector<1,1>+<4,-3>
How can a null vector be a vector if there is no direction?
It has magnitude 0 and a direction and obeys vector laws, so is a vector
How can you find the direction of angular momentum if the position vector and force vector lie on the plane?
By finding the direction of angular velocity because it's always parallel to it.
Is a torque vector quantity?
Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
How a vector represent distance and direction?
A vector is like an arrow. The length of the vector represents the magnitude (distance, speed, whatever) while the direction is shown by the direction of the arrow.A vector is like an arrow.

Is north a vector direction?
"North" is a valid direction, but for a vector, you would also need a magnitude.
Is the acceleration of a rocket a vector or scalar?
It is a vector. A scalar has only magnitude. A vector has magnitude and direction.Acceleration is a vector because it has magnitude and direction. That's why an object can be said to be accelerating if it has a circular rotation and a constant speed; even though it's speed isn't changing, it's direction constantly is. Displacement (s), velocity (v), and acceleration (a), are vectors because they have both magntude and direction.
