13. ### 2 Mini Q.

Hi king:smile: O.K. used (I) for Contour = sum of Curves , and Closed and used (II) for any Curve Q.2 Now z1(t)=t , 0=<t=<5 z2(t)=5+it , 0=<t=<5 z3(t)= t+5i , 5=<t=<0 z4(t)=it , 5=<t=<0 :yuck:
14. ### 2 Mini Q.

Dear Dick مرحبا سعيد يرؤيتك 1) I can not find an answer in books,In books sometimes use pattern,Sometimes using type IIusing In your answer: They both indicate integral over the contour Do you clarify if possible 2) C1:z(t)=t , 0=<t=<5 C2:z(t)=5-t+5i , 0=<t=<5 C3:z(t)=5-t+5i ...
