C=15 degrees sorry if I’m not right
Answer:
Step-by-step explanation:
The Laplace's equation in rectangular coordinates is:
For the solution, we assume that u can be write as
Replace
Divide
The only way that this can be true, is that every term is the same constant, so we say that
With a constant.
Now, we solve every part. For
The solution is:
For
Is the differential equation for a harmonic oscillator, so the solution is
Now, we evaluate the boundary conditions:
The other
For :
So,
The other condition:
So,
Answer: area= 38, perimeter=34
