Homework Statement
Convert the following expression into sum of products and products of sums
(AB+C)(B+C'D)
Homework Equations
Distributive Property
The Attempt at a Solution
for product of sums it would be (AB+C)(B+C'D) since it is already in this form.
When calculating sum of...
When I originally posted this I could think of no better way to phrase this with my limited understanding of the subject matter. The question was about vectors in general and what exactly they are. Why in something like a simple 2x2 matrix would I plot the values of the columns to get a vector...
I have spent a good amount of time trying to understand how vectors relate to a system of linear equations. Much of the information I find online are proofs which simply confuse me. I love math, but it is an extremely difficult relationship for me. If anyone could put vectors into simple terms...
Find the inverse of the rotation matrix
cos(theta) -sin(theta)
sin(theta) cos(theta)
I have no problems finding the inverse of a standard 2x2 matrix, however I am confused by the trig functions.
I guess the determanent would be 2cos(theta) and I would end up with...
