  \footnotesize \quad \:  \int(8 {x}^{2}  + 7 {x}^{3}  + 4x + 2)dx \\

 \footnotesize =  \int8 {x}^{2} dx +  \int7 {x}^{3}  +  \int4 {x}^{1} dx +  \int2dx \\

 \footnotesize = 8(2 {x}^{2 - 1} ) + 7(3 {x}^{3 - 1} ) + 4(1 {x}^{1 - 1} ) + 2(0)

 \footnotesize = 8(2x) + 7(3 {x}^{2} ) + 4( {x}^{0} ) + (0)

 \footnotesize = 21 {x}^{2}  + 16x + 4

 \footnotesize \quad \:  \int(7 {e}^{x}  + 2 \sin \: x)dx \\

 \footnotesize =  \int7 {e}^{x} dx +  \int2 \sin \: x \: dx \\

 \footnotesize = 7( {e}^{x} ) + 2( -  \cos \: x)

 \footnotesize = 7 {e}^{x} - 2 \cos \: x
