The origin of vectors
Vector can enter mathematics and develop, first of all, we must talk about the geometric representation of complex numbers. /kloc-At the end of 0/8th century, Norwegian surveyor wiesel first expressed complex numbers with points on the coordinate plane, and defined vector operations with geometric complex operations. Points on the coordinate plane are represented by vectors, and the geometric representation of vectors is used to study geometric problems and trigonometric problems.
People gradually accepted the complex number, and learned to use it to represent and study the vector on the plane, so the vector quietly entered mathematics.
