這個(gè)函數(shù)怎么求積分0到75度的積分?
2*m*(0.15*tan(b)+a)^2/((15-100/39.27^2)*(((k(1)+k(2))*0.15*tan(b)-l*sin(b))/m*(0.15*tan(b)*sin(b)+a))^0.5)*(((k(1)+k(2))*((0.15*(sec(b))^2-l*cos(b))*(0.15*tan(b)*sin(b)+a)-(0.15*tan(b)-l*sin(b))*0.15*((sec(b))^2*sin(b)+sin(b)))/(2*m*(0.15*tan(b)*sin(b)+a)^2*((15-100/39.27^2)*(((k(1)+k(2))*0.15*tan(b)-l*sin(b))/m*(0.15*tan(b)*sin(b)+a))^0.5))));
