do you understand the concept of limit?

anonymous · Answer

I think I do. Hehehe

experimentx · Answer

tell me what you understand?

anonymous · Answer

oh I take it back. Haha i don't really know limits that much. All I know is that when I evaluate, I just substitute the value in the "as x approaches" in the function. Except of course when it's indeterminate. When it's indeterminate, i manipulate the function for it to be not indeterminate. =)) that's all i know. Haha
