Answering this question, I would start by talking about when I have lunch and by comparing it to people in Italy. It is a good way to show that you know how to say the time in Italian and you know some as...

Proteins are made up of the primary structure, secondary structure and tertiary structure. Some proteins may also have a quaternary structure. The primary structure is the specific sequence of amino acids...

By putting u=cosx and v’= e^x , use the by parts formula to get:∫e^(x)(cos(x)) dx = cos(x)e^x - ∫-(e^x)sin(x) dx. Use by parts again on the second term to get ∫ =cos(x)e^x + sin(x)e^x - ∫e^(x)(c...
