How to plot this type of function?

[Walter Roberson]

Strange, I could have sworn I saw someone post code for this involving fplot3()

That was me LOL

Answer 1

t = linspace(-5,5) ;
x = exp(t) ;
y = 1-exp(-t) ;
z = atan2(y,x) ;

plot(t,z)

syms t 

x = exp(t) ;
y = 1-exp(-t) ;
z = atan(y./x) ;

fplot(z)

Note that atan(y./x) is usually better done as atan2(y, x) . The difference is that atan2() will get the right quadrant.

@Walter Roberson agree.....edited the code.
