I wanted to find out the value of the follwing double integral

F(x,y) = (2*(22/7)*59552000)*(0.75-(0.075*x))/((x.^5)*(exp(14387.752/(x*(1000-600*y)))-1))

in the intervals 1-10 on x and 0-1 on y

Hello Sivaramakrishnan,
Have u treated this problem as initial value problem,if so u may consider Euler's Method(Adams Bash Forth first order method) an example of the same is given below which u may try for ur question.However pl note that this is in javacodes.and also a similar one to ur problem though not the same function(x,y)
As Always

As there is no reply to the above i am forwarding yet another concrete example,coded (only in java)that should suffice ur question.You may please replace the current formula in findf() method in the program with your new formula and then try to compile and execute , and see if it works
Thanking You
As Always
