Yes, I got to f=2.*x.*sin(6.*pi.*x+exp(2.*x.*cos(6.*pi.*x.))); but something is wrong and I can't quite put my finger on it

Answer 1

1. Read about sin, cos
2. Read about exp.
3. Read about linspace.

Example: If I want to write a function for sin(pi*x)

m = 100 ; 
x = linspace(0,2,m) ; 
y = sin(pi*x) ; 
plot(x,y)

[Iurie Obodeanov]

I got to f=2.*x.*sin(6.*pi.*x+exp(2.*x.*cos(6.*pi.*x.))); but something is wrong, I don't know what

[KSSV]

Show us the whole code which you tried....so that we cna help you.

m = 100 ;  % give your value 
x = linspace(0,1,m) ; % give your range for x 
f=2*x.*sin(6*pi*x+exp(2*x.*cos(6.*pi*x)));
plot(x,f)

In your line..you have used x. this is not correct. You need not to use pi.*..as pi is only a single number.

I would assume from the equation image that the exp( ) stuff maybe should be outside of the sin( ) stuff. E.g.,

f = 2.*x.*sin(6.*pi.*x) + exp(2.*x.*cos(6.*pi.*x));
