i am having trouble with some hw problems in my linear algebra course... the book is brescher and the teacher is sort of a rambling nutcase whose presentation of material is anything but 'linear', and very difficult for me to follow. similarly the book contains problems that i can't seem to suss out based on the chapter. this is for the hw for a section on 'introduction to linear spaces' which mostly gave examples of 'how to tell if this is a subspace of this'....(adsbygoogle = window.adsbygoogle || []).push({});

the problem is: find the matrix A (a vector with four components) of the linear transformation T(f(t)) = the definite integral of f(t) from 3 to -9 with respect to the standard bases for P_3 and R. there is nothing in the chapter about integrals as matrices, and what does it mean to have two bases at once...?? thanks
