I want to do remain sum form 0 to 3 or sqrt(x+1) from the left with 10 to 100 sub interval,
the graph have to go from small to big but somehow my code go from big to small. please let me know what i did wrong, all the equation are correct
I use the exact way on python and it gave me the graph the graph that I want
hold off
sumvec1 = []
for n = 10:100
sum = 0;
width = ((3 - 0)/n) ;
for c = 0:n
base1 = (width) * c- width ;
height = sqrt((base1 +1));
sum = sum + (width * height);
end
sumvec1(n-9) = sum;
end
figure;
i = 1:length(sumvec1)
scatter(i,sumvec1)

Try this (edited)
hold off
sumvec1 = [];sum = 0;
for n = 10:100
width = ((3 - 0)/n) ;
for c = 0:n
base1 = (width) * c- width ;
height = sqrt((base1 +1));
sum = sum + (width * height);
end
sumvec1 =[ sumvec1 sum];
end
figure;
i = 1:length(sumvec1);
scatter(i,sumvec1)
