The widening gap between known protein sequences and their functions has led to the practice of assigning a potential function to a protein on the basis of sequence similarity to proteins whose function has been experimentally investigated. We present here a critical view of the theoretical and ...

This paper focuses on in-course sample diagnostic questions relating to elementary logic, and the two concepts of limits and continuity of a function. These are for students who choose to take a course on differential calculus, in a South African context. However, the diagnostic questions could ...

Compare your answer with the one in the summary at the end of this section. We will introduce some special vocabulary in order to be clear what we mean when talking about functions. The domain of a function If f ( x ) = x 2 and the values of x are 0, ±1, ±2, ±3, …, ...
If we divide R into mn subrectangles, \iint _{R}k\d A\approx\sum\limits _{i=1}^{m}\sum\limits _{j=1}^{n}f(x^{*}_{ij},y^{*}_{ij})\Delta A for any choice of sample points (x^*_(ij),y^*_(ij)). But f(x^*_(ij),y^*_(ij))=k always and ∑limits _(...
