After I set t and f equal to a value how do u solve the function?

You have to give a range of t values to plot this graph by this command t = initial value : incremental value : final value;
In other words by this command we have created a vector t that consists of all values between 0 to 10.

Plot(t, x)

MATLAB is case sensitive now so Plot() would only be accepted on old versions of MATLAB. Exact dates are not coming to mind... I want to say since about r2006a.

N =[]; %initialising an array
for j = 1:n %loop to get n different values of x
x = 4*(cos((0.5*sqrt(-1)*pi)/(n+1)).^2);
N = [N x]; %appending values of x in initialised array
end
%Here, i have assumed set as an array of values.
%And we need to provide value of n too.

) Given a vector, t, of length n, write down the MATLAB expressions that will correctly compute the following:
a) ln(2 + t + t 2 )
b) e t (1 + sin(2t))
c) cos 2 (t) + sin 2 (t)
d) sec 2 (t) + cot(t)
- 1 - Test that your solution works for t = 1:0.5:4
- Plot the expressions -
Label the plotted figure with the following
o Title ( i.e.: Plot of ln(2 + t + t 2 ) )
o Axis
o Figure caption (your name and ID)

As Walter stated this isn't an answer to the original question. In addition, this sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.
If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.
If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

(sqrt(z2) + (xele - x2))/c
or possibly
(sqrt(z2 + (xele - x2)))/c
or possibly
sqrt(z2 + (xele - x2)/c)
depending on how far the square root is intended to extend.
