00:06In this video we are going to find the double integral of a function and its graph in Matlab.
00:11As an example, I will take a function from the book of analytic geometry, from the lemma we begin with
00:18To make a comment in Matlab, you first type the percentage followed by the text, like this:
00:23double integrals now to define the variables we write sims in x and y and we write the function of the
00:37book that we want to know its double integral, that is, x squared plus y squared minus 1, which
00:43Multiply y squared minus 4x and it can be seen that the function is entered correctly
00:53We write its general equation to determine its double integral or its antiderivative.
00:58For the double integral, we will try the function, we find the integral of y, then in x, and so on.
01:05obtains its double integral we write next te equal to char of the function in efe in char
01:10We also convert numbers to characters to type capital letters.
01:15The integral found we then write surfe in the function t and we also write sold on
01:28And we also write that capital letter t, that creates a three-dimensional surface graph
01:36and we obtain the graph of the function and its graph of the double integral found
01:47That's all. If you found the video helpful, don't forget to subscribe.
