Suppose one wishes to plot e^x, x, and log(x) on a single graph so one
can talk about inverse functions. I have tried (in order to avoid the
log of absolute x from showing up on the plot):
plot2d([%e^x,x,[parametric,t,log(t),[t,0,5]]],[x,-5,5])
However, I get:
bob@euler:~$ maxima
Maxima restarted.
(%i1) plot2d([%e^x,x,[parametric,t,log(t),[t,0,5]]],[x,-5,5]);
Maxima encountered a Lisp error:
Error in <= [or a callee]: T is not of type (OR RATIONAL LISP:FLOAT).
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
(%i2)
Where am I going wrong?
Is there away to separately retrict the domain of two plotted functions
without using parametric plotting?
Maxima 5.9.1-9
Thanks, Bob
