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...
