cosine code snippets in matlab

compute value of z=cos(x/y)*cos(y)+(y/10)-(x/5) for all grid points (x,y) in matlab

how to calculate the cosine of an angle in degrees in matlab

numerically differentiate cos(x) at x = 1 using the following step size: 0.1, 0.05, 0.01, 0.005, and 0.001. use 1st order accurate forward 1st derivative approximations. return the error and the value in matlab

plot a function using sine and cosine that will start at point [0,0], go to [2,6], from there to [8,0] a from there to [13,15] in matlab
