In this problem, we have a limit.
00:03
So the limit as x get closer to 1 from the positive side of x squared divided by x minus 1 square.
00:11
So what does it mean x goes to 1 from the right end side? it simply means that if this line represent the real number and we have 1, we only take values of x coming from the right end side of 1.
00:26
So values of x, which are strictly greater than 1, meaning that x minus 1 is positive it will always be positive the therefore the limit as x get closer to 1 from the right end side of x minus 1 is 0 1 minus 1 but 0 plus so it's maybe not the perfect notation but it's just proof that um all all the numbers that we would get with this positive sign, all that would get closer to zero without ever going, without ever having a negative number.

Same thing if we, and if we take that the same limit, except we square everything, we would still get zero but positively.

So the square doesn't change the limit...
