:dotP(list1, list2) :dotP(vector1, vector2)
This takes the dot product of two vectors.
The vectors can be any size, but they must be the same size. Additionally, instead of a vector, lists with the same restrictions can be used.

:Disp dotP({1},{1}) :Disp dotP([√(5)∠90°-tan-1(1/2)],[√(5)∠tan-1(1/2)]) :Disp dotP([1,3,-5],[4,-2,-1])
This will print the three dot products using three acceptable kinds of input. It will display 1
