Solving problems or issues in an economic or technological context, often involves a little math. Systems of linear equations have to be solved. The matrix algebra taught in this course , can be useful.
To discuss setting up relationships between quantities , for example economics or physics , to recognize and to form new relationships we learn to use differential and integral calculus ( derivatives and integrals ) .
Many quantities in physics are expressed as vectors. To calculate or reason with this quantities, vector algebra is needed.
