it is really tedious, probably impossible, to do the following equation using a calculator. Please note that cosine and sine functions are in degrees
the result should b a scalar value if i am right?

The equation seems to be missing from your Question ?
I see you have changed the wording of your question a little, and given the note about degrees, but the equation itself isn't there yet ?
sry, i just reuploaded the image, could you now see the equation?
No products are associated with this question.

k = 0:65119;
sum( cosd(3.6*k) .* sind(3.6*k) ).^2
cool, it really works. actually, i just manage to obtain the result using
function [S] = sum1(n)
S = 0; % Initialize sum to zero
k = 0; % Initialize index to zero
% loop for calculating summation
while k <= 65119
S = S + cos(3.6*k*pi/180)*sin(3.6*k*pi/180); % add to summation
k = k + 1; % increase the index
and then square the outcome, and get the answer as urs.
cool, urs looks tidier. many thx
