Transcript

in this video we're going to talk about how to calculate the volume of the parallelepiped given the adjacent edges v w and u which are vectors so how can we do this well let's begin by drawing a picture so here we have the x-axis the y-axis and the z-axis now let's say that vector v is along the x-axis and let's say that vector w is along the y-axi...
