y = (exp(x)/ sin(x)) + 0.3;
plot(x,y)

You are missing . before /. See:

https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html
x = -10 : 0.01 : 10;
y = (exp(x)./ sin(x)) + 0.3; % use ./ instead of /
plot(x,y)

It's because you used a matrix division instead of an element-wise division to calculate y. Try this instead:
y = (exp(x)./ sin(x)) + 0.3;
Note the use of ./ in place of just / in the formula.
See this documentation for more details.
