Vectors:magnitude with direction

a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.

Deriving VectorsBy deriving vectors you can go from a position vector to a velocity vector, velocity to acceleration, and so on.Calculator>use the numerical derivative function on your calculator to derive each vector seperately.Non-Calculator>Derive each vector seperately by hand, using power rule, chain rule, etc.

Practice Here!

Remember that the derivitive of a funtion Y(x) is Dy/Dx

>Derive your individual functions with respect to 't', ergo [Dx/Dt , Dy/Dt] >Divide Dy/Dt by Dx/Dt so that the 'Dt's cancel

Converting to a derived function

vectors are commonly used in navigation

Common ErrorAlert!Do not divide by Dx/Dt twice! this is not parametric!
