Answer the following statement(s) true (T) or false (F)
1. In general, engineering problems are mathematical models of physical situations. 2. Mathematics is a language that has its own symbols and terminology. As an engineering student, you need to learn mathematical symbols and their meanings. 3. Greek alphabetic characters quite commonly are used to express angles, dimensions, and physical variables in drawings and in mathematical equations and expressions. It is therefore very important to be familiar with these characters in order to communicate with other engineers. 4. For many engineering situations, nonlinear models are used to describe the relationships between dependent and independent variables because they predict the actual relationships more accurately than linear models do.
