In this problem, we're given this following equation, which is the general format of a hyperbolo.
00:08
And we ask, for what values of a and b are the asymptotes of our graph perpendicular to one and other? so if this is the general shape of a hyperbolo, we've said to find this angle between it.
00:27
We want it to be perpendicular or 90 degrees.
00:29
Well, let's think about it.
00:32
When a and b are both equal to 1 in the regular format, you have the following.
00:40
We have like this left side and the right side.
00:46
And then the asymptotes are technically perpendicular because based on symmetry, each asymptote splits the angle created by the x and the y axis into halves of 45 degrees.
01:02
Therefore, this will be four.
01:03
45, this will be 45, overall will be perpendicular or 90 degrees.
01:09
So if a equals to b, then we will have perpendicular asymptot.
01:22
And why is that again? again, the slope of asymptotes are positive negative b over a...
