And the slope of line CB is mathematically evaluated as
Now for lines that are perpendicular to each other then the product of their slope should be equal to -1
So if
Then
i,e
Critical points occur when
Check the sign of the second derivative at each critical point to determine the function's concavity at that point. If it's concave (
You have
and so
This means a maximum of
