When exactly do you know the apply the deformation of contours formula and cauchy - goursat theorem.

Mathematics often discovers theorems and later, another subject finds out "oh wow, this actually applies to this physics/biology/pharmacology/engineering problem.

For the most part, you wont know when to apply certain formulas until you need to solve an equation and you find out a correlation between a sequence/formula and the problem

0.16

Step-by-step explanation:

You can reduce this fraction

8/50

4/25 = 4 ÷ 25 = 0.16

I hope this helps! c:
