g=(1-3*y^2.1)/(sin(y)^2*(4+y))>> diff2_g=diff(g,y,2)diff2_g =-693/100*y^(1/10)/sin(y)^2/(4+y)+126/5*y^(11/10)/sin(y)^3/(4+y)*cos(y)+63/5*y^(11/10)/sin(y)^2/(4+y)^2+6*(1-3*y^(21/10))/sin(y)^4/(4+y)*cos(y)^2+4*(1-3*y^(21/10))/sin(y)^3/(4+y)^2*cos(y)+2*(1-3*y^(21/10))/sin(y)^2/(4+y)+2*(1-3*y^(21/10))/sin(y)^2/(4+y)^3Does simple simplify in this case?132
