Many of the properties of differentiation from theCalculus I: Derivativesalso apply to vector-valued functions. ( t ) T(t)T(t) The antiderivative of a vector-valued function is found by finding the antiderivatives of the component functions, then putting them back together in a vector-valued...
Our first step in studying the calculus of vector-valued functions is to define what exactly a vector-valued function is. We can then look at graphs of vector-valued functions and see how they define curves in both two and three dimensions....

However, now that we have multiple directions to consider (x, y and z), the direction of greatest increase is no longer simply “forward” or “backward” along the x-axis, like it is with functions of a single variable. If we have two variables, then our 2-component gradient can spec...

For example, we can say that North and East are 0% similar since(0,1)⋅(1,0)=0. Or that North and Northeast are 70% similar (cos(45)=.707, remember thattrig functions are percentages.) The similarity shows the amount of one vector that “shows up” in the other. ...
