# How to find out the difference between M.determinant(), M.det() and det(M)?

I am quite new to sagemath, but an experienced mathematician ... so I tried computing determinants for a given Matrix M and found different solutions. I found that M.det() is short for M.determinant() after searching the index and going further from there. But I did not find something for the syntax det(M). Inspire of being not a programmer, I am interested in

a) where could I search to find the difference? b) what is the difference, if any?

Many thank! Doris
