I have no problem, normally, to introduce the funtions in the program, but I have different result when I use Origin 6.0 or 7.5 and I don't known if I may be wrong by introducing the equations, or the funtions are very longer, or the symbols that I use to introduce my funtions are wrong. My kind of funtions are as follows: Complejo ML: y=Ao+(Af-Ao)/(2*Co)*(Co+x+1/K-((Co+x+1/K)^2-4*Co*x)^(1/2)) Complejo ML2: N=-1-K1*x+((1+K1*x)^2+(8*Co*K1^2*K2*x))^(1/2); y=N*((Ao/Co)+b*K1*x+(Af*N/(2*Co)))/(4*K1*K2*x) Complejo M2L: y=(Ao+(Co*b*K1*x)+(Af*B*x^2))/(1+K1*x+B*x^2) Complejo M3L2: N=-1-K1*x+((1+K1*x)^2+(8*Co*K1^2*K2*x^3))^(1/2); y=N*(Ao+b*Co*K1*x+(Af*N/2))/(4*K1^2*K2*x^3*Co) OR Ecuación ML y=Ao+(((Af-Ao)/(2*Co))*(Co+x+(1/K)-((((Co+x+(1/K))^2)-(4*Co*x))^(1/2)))) Ecuación M2L y=Co*((Ao/Co)+(b*K1*x)+(Af*K1*K2*x^2/Co))/(1+(K1*x)+(K1*K2*x^2)) Ecuación M3L2 y=((-1-(K1*x)+((((1+(K1*x))^2)+(8*Co*(K1^2)*K2*(x^3)))^(1/2)))/(4*(K1^2)*K2*(x^3)))*((Ao/Co)+(b*K1*x)+((Af*(-1-(K1*x)+((((1+(K1*x))^2)+(8*Co*(K1^2)*K2*(x^3)))^(1/2))))/(2*Co))) Ecuación ML2 y=((-1-(K1*x)+((((1+(K1*x))^2)+(8*Co*K1*K2*x))^(1/2)))/(4*K1*K2*x))*((Ao/Co)+(b*K1*x)+((Af*(-1-(K1*x)+((((1+(K1*x))^2)+(8*Co*K1*K2*x))^(1/2))))/(2*Co))) I hope you can help.
