Find  (dy/dx)  if  y = 3sin^2 (x−5x^2 )
$$\mathrm{Find}\:\:\frac{{dy}}{{dx}}\:\:\mathrm{if}\:\:{y}\:=\:\mathrm{3sin}^{\mathrm{2}} \left({x}−\mathrm{5}{x}^{\mathrm{2}} \right)\: \\ $$

 (dy/dx) = 6(1−10x)sin (x−5x^2 )cos (x−5x^2 )    = (3−30x) sin (2x−10x^2 )
$$\:\frac{\mathrm{dy}}{\mathrm{dx}}\:=\:\mathrm{6}\left(\mathrm{1}−\mathrm{10x}\right)\mathrm{sin}\:\left(\mathrm{x}−\mathrm{5x}^{\mathrm{2}} \right)\mathrm{cos}\:\left(\mathrm{x}−\mathrm{5x}^{\mathrm{2}} \right) \\ $$$$\:\:=\:\left(\mathrm{3}−\mathrm{30x}\right)\:\mathrm{sin}\:\left(\mathrm{2x}−\mathrm{10x}^{\mathrm{2}} \right)\: \\ $$
