MathsBio is quite a large Field .It is an interdisciplinary branch having utility in lot of branches in biology like Biophysics, biomedical, genetics and molecular biology.Applied Mathematics is generally used in modelling and understanding biological phenomena where we have to deal with large amount of data. Like use of graph theory for analysing biochemical networks. System biology one of emerging field uses a lot of mathematics.

You should pick book depending on field you want to use mathematics though having knowledge of elementary biology is necessary. I am suggesting some book which cover wide application of mathematics in biology.

MathsBio is quite a large field. It is an interdisciplinary branch having utility in a lot of branches in biology like biophysics, biomedical, genetics and molecular biology. Applied Mathematics is generally used in modelling and understanding biological phenomena where we have to deal with large amount of data, for example the use of graph theory for analysing biochemical networks. Systems biology is an emerging field which uses a lot of mathematics.

You should pick a book depending on the field in which you want to use mathematics, though having knowledge of elementary biology is necessary. I am suggesting some books which cover wide application of mathematics in biology.
