f(x) = x + 1/x
f(1 + 3i), lets just sub x by 1 + 3i
f(1 + 3i) = 1 + 3i + 1/(1 + 3i)
Doing the sum (1 + 3i) + 1/(1 + 3i) we get ((1 + 3i)² + 1)/(1 + 3i)
So:
f(1 + 3i) = (1 + 2.1.3i + 9i² + 1)/(1 + 3i)
f(1 + 3i) = (6i - 7)/(1 + 3i)
f(1 + 3i) = 11/10 + 27i/10
Answer:
Yes! See explanation below!
Step-by-step explanation:
If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.
Ex:
Answer:
1
Step-by-step explanation:
5=3d+2
subtract the 2 on both sides
3=3d
divide 3 on both sides
you get 1
