I am not able to solve the given integration function. The screenshot of given is attached and the code is given below
Thank you
for j=1:100
x(j)=linspace(0,0.025,101);
R(j)=linspace(0,0.4,101);
f=0.025;
syms x
b(j)= int(R(j)-sqrt(R(j).^2-x(j).^2),0, f);
c(j)=sqrt((1/f)*b(j));
end

yes sir
for given R=0.4, f=0 & 0.025, x=0:0.001:0.025,
what will be the value of σ for each x
Kundan Prasad on 16 Dec 2021
here f=0.025

This cannot work:
x(j) = linspace(0,0.025,101);
On the left is a scalar and on the right a vector with 101 elements.
Seeing only the invalid code does not clarify its intention. What is the purpose of the loop?

what need to be change in code. Please clarify??
Thank you

I cannot fix the code such that it does, what you want, as long as you do not clarify what you want to achieve. I ask again: What is the purpose of the loop? I'd expect RT to be a constand and x to be a symbolic variable. Then there is no need for a loop.

indeces should have to match in both side and be compatable as well
