I have to do a double integral of the function sin(x) + cos(y) dxdy in IML , using a Monte Carlo simulation, with vectorized code. Truly, I do not know how to do it.

Please specify the domain of integration.

 

There are two common ways to use Monte Carlo to estimate integrals, so you'll have to look at your notes/textbook to decide which you should use. In one (the average-value method), you generate points uniformly on a 2-D domain and evaluate the function at each random location. In the other method (the volume method), you generate 3-D points and estimate the probability that a random point is under the graph of the function.

 

Here are some articles that use the average-value method. Study and understand the 1-D example before you attempt 2-D.
