Answer:
Step-by-step explanation:
Its (1,3) and (-3, -2)
We have

So

The rational term vanishes as <em>x</em> gets arbitrarily large, so we can ignore that term, leaving us with

and this happens if <em>a</em> = 1 and <em>b</em> = -1.
To confirm, we have

as required.
Since complementary angles add up to 90 degrees, we simple take

and simplify it to
