Cbe the circle of radius 7 centered at the origin oriented counterclockwise. evaluate contour integral subscript upper c superscript baseline bold upper f times d bold r by parameterizing c.

Step-by-step explanation:

Given that a circle C of radius 7

To find:

As NO function is given so we suppose it to be:

Parametric equations:

Each point on circle can be then found as

From (2) dr can be found as:

From (2) and (3)

-2 is the right

won't that be plagrisim thought?

step-by-step explanation:
