Simply put, a vector is 2 dimensional.
Think of speed - it is only one dimensional. It is not a vector, it is a scalar. It is measured in a scale, most commonly noticed when inside a vehicle. You are travelling at 100km/h (60mph)
Vectors are 2 dimensional, they have a magnitude and a direction.
Think of velocity, as an arrow - imagine you are travelling at 60 mph in a northerly direction, your arrow would be pointing to the notth, with a magnitude of 60mph, If you were travelling at 60mph in a southerly direction, your velocity vector would be pointing towards the south, the exact opposite of your vector if you were travelling in a northerly direction.
However the speed in these two scenario's, speed not being a vector, remains exactly the same, 60mph.

Is rotation scalar or vector?
Rotation is a vector having a direction and magnitude.
Positive rotation of a vector is?
counterclockwise
Why only cos theta is used in vector functions?
It's not. Cos(Θ) only gives you the x-component of a vector. In order to find its y-component, you also need to use sin(Θ).
What is the meaning of delta in math?
Typically, delta means "change in" in math.
What trig functions is useful for finding the horizontal componet of a resultant vector?
There are no useful ones on the list that follows the question.
