-i/2

Step-by-step explanation:

Recall that i² = -1.

z² + 1 factors into (z + i)(z - i), and so the original expression reduces as follows:

    z - i               1

= for z not equal to i

(z + i)(z - i)       z + i

Now attempt to find the limit as z approaches i of the above rational fraction.   The limit is

    1            1                                                                  1

=     which, if rationalized, becomes   (-i), or  -i/2

  i + i        2i                                                                2

answer: get jesus in your life

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
