Hi!

I have a function here :

this is when 0<= x<=a

when a<= x<=b

I have to to sketch this.... Can I do this without giving any numerical value to the parameters a and b? I'll plot it as a function of x

Here is my attempt sorry if it's childish, I'm not professional

clear all

clc

syms a b x

Psi1= sqrt(3/b)*x/a;

Psi2=sqrt(3/b)* (b-x)/(b-a);

plot(x,Psi1)

hold on

plot(x,Psi2)

"Can I do this without giving any numerical value to the parameters a and b?"

Of course: write a function and then call fplot.

No, you cannot do this without giving numerical values to a and b.
