Realpart

Function: realpart (<expr>) Returns the real part of <expr>. realpart and imagpart will work on expressions involving trigonometic and hyperbolic functions, as well as square root, logarithm, and exponentiation.

a:2;
b:0.45;
c:-0.3;
d:1.27;
f:0.25;
realpart(-(log(a*c)/(b+d)));
x0:realpart(log(a/c)/(d-b));
diff(1/x);
a*exp(b*x0)+c*exp(d*x0);
realpart(1-(c/a)*exp(x0*(d+b)));
plot2d( [  log(x), -log(1-exp(x)), -log(1+(c/a)*exp(x*(d-b))), x*b-log(f/a),[parametric, realpart(x0), t, [t, -10, 10]]],[x,-5,5]);
