Hi all,
I was getting wrong answers for the integeral of the next expression,
>> syms x >> f(x)=sin(x)+2*cos(x) f(x) = 2*cos(x) + sin(x) >> F=int(f(x))
The result integral came as:
F =
-2*cos(x/2)*(cos(x/2) - 2*sin(x/2))
So I tried to operate each term separately to get the right answer, which is different than the first one.
>> F2=int(sin(x))+int(2*cos(x)) F2 = 2*sin(x) - cos(x)
I tried the web version of matlab to check possible bugs within the version I'm using, but I found the same error anyway.
Maybe I am doing it wrong. Please help.
