All right, makes sense. I knew about the lim x->0 , sin x / x = 1, but I had forgotten about the cosine one. How convenient that I kept getting the right answer no matter how wrong I did the problem, lol. Thanks again!
You can solve the next problem in two ways and yet getting the wright answer, but the of one of them is wrong!
1+1/1 = 2
If you start with devision operator first you doing the wright thing and get 2
...and if you start with adding... you still get 2(But it THE WRONG WAY!)
