y=x(√(16−x^2 ))+16arcsin((x/4))  (dy/dx)=(√(16−x^2 ))−((2x^2 )/(2(√(16−x^2 ))))+16((1/4)/( (√(1−(x^2 /(16))))))  =(√(16−x^2 ))−((x^2 (√(16−x^2 )))/(16−x^2 ))+((16(√(16−x^2 )))/(16−x^2 ))  =(√(16−x^2 ))+(√(16−x^2 ))(((16−x^2 )/(16−x^2 )))  =2(√(16−x^2 ))..
y=x16x2+16arcsin(x4)dydx=16x22x2216x2+16141x216=16x2x216x216x2+1616x216x2=16x2+16x2(16x216x2)=216x2..
