MATLAB: Matlab calculates cosine different from the calculator cos If i calculate cos(1) in matlab I get ans=0.5403 whereas my calculator says 0.9998, what am I missing? Best Answer Your calculator is calculating in degrees. By default MATLAB calculates in radians: MATLAB = cos(1)Calculator = cosd(1)produces: MATLAB = 0.540302305868140Calculator = 0.999847695156391Use the MATLAB cosd function (and the other ‘d’ trigonometric functions) to calculate in degrees.
