Question

Evaluate the given integral where C is the left half of the unit circle in ccd.

Sc z sin(z²) dz
Transcribed Image Text:Sc z sin(z²) dz
Expert Solution
Step 1

Note:- In given problem you mention "ccd" but one short form has different different full form. So, please always complete word so that we could use exactly that method. Thank you

 

Given integral is

Cz sinz2 dz

C is left half of the unit circle.

For a circle,  z=reiθ

As, given circle is unit circle so r=1 then

z=eiθ;    -π2θπ2

Also, 

dz=i eiθ dθ
