1) What is a meaning of (homotopic) in Cauchy's theorem for the sets'?

and in sets what is t,s where H(t,s)

2)

(-1)^1/2*(-1)^1/2 = (-1*-1)^1/2=1^1/2=1=/=i^2

3)

In Integral functions' by Reiman Sum

is delta x

It handles any inclination at the point

Concluded that by diminishing its value to zero

## Homework Equations

## The Attempt at a Solution

2) (-1)^1/2*(-1)^1/2 = i(1)^1/2*i(1)^1/2=i*i=-1=/=1

But the former right way

The result is wrong

logic Sports saysThe right does not lead to an error
