1. Boolean Algebra

sum of products Oh yes I see! (AB+C)(B+C'D) = ABB+ABC'D+CB+CC'D = ABB+ABC'D+CB+0D = ABB+ABC'D+CB =AB+ABC'D+CB Then this would be in the correct form!
2. Boolean Algebra

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...
3. Concept of vectors

Thank you Mark44 and trambolin for your responses. I feel much more secure with the idea of vectors now. Excellent job!
4. Concept of vectors

Thank you very much slider142 :smile:
5. Concept of vectors

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...
6. Concept of vectors

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...
7. Finding inverse of matrix with trig values

Thank you for all the responses. The subject has been clarified and I appreciate the assistance provided.
8. Finding inverse of matrix with trig values

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...
