A = -0.4161 -1.0000 0.8660 -0.6235 0.0044. Compute the cosine function for the numbers converted to symbolic objects. · symA = [ cos(2), -1, 3^(1/2)/2, -cos((2* ...

Cosine Function for Numeric and Symbolic Arguments. Depending on its arguments, cos returns floating-point or exact symbolic results. Compute the cosine function for these numbers. Because these numbers are not symbolic objects, cos returns floating-point results. A = cos ( [-2, -pi, pi/6, 5*pi/7, 11]) A = -0.4161 -1.0000 0.8660 -0.6235 0.0044.

20.01.2020 · Considering this, what is Matlab COSD? Y = cosd(X) is the cosine of the elements of X , expressed in degrees.For odd integers n , cosd(n*90) is exactly zero, whereas cos(n*pi/2) reflects the accuracy of the floating point value of pi .See Also. Similarly, what is COS in radians? Definition of cosine The cosine of an angle is defined as the sine of the complementary angle.

Show activity on this post. I have collected this data of angles and intensities in lab to show Malus law so I have to fit the I as I=I0*cos^2 (theta). I can't succeed with the cftool because it shows a curve totally different from my data, and I can't get a code that works. This is the data I got: theta = [90, 110, 130, 135, 150, 170, 180, 190 ...
