Special topics course offered in Summer 2018 by Christopher Heil and Shahaf Nitzan on "Real Analysis for Engineers". 

This course can be taken in place of MATH 6337, Real Analysis, to satisfy the prerequisite for MATH 6241, Probability I. 

This course cannot be used for credit at the same time as MATH 6337.
