I remember that - this is definite integral.
But I think I have not definite integral. I have tried to solve this problem using this pattern:
But You said mine solutions from previous posts based on this pattern were wrong.
So now I have solution by skeeter - what next ? As I understand this is some other method based on definite integral and now I can't use above pattern ? So what should I do now ?
thx skeeter - Your solution is different than solution which I know and Your solution is easier
As I understand in Your solution we must count definite integral and then
? Only that ?
So maybe mine pattern is for count area under curve ? I had integrals 3. years ago and I remember nothing.... :/
