Hello,
if express means simplify than
Answer:
Step-by-step explanation:
We are trying to evaluate this integral.
The first thing that we have to do is understand this region in the plane.
If you graph it looks something like the photo I join.
Now we need to describe that same region in polar coordinates.
That same region in polar coordinates would be
Now remember that when we do the polar transformation we use the following formula
Then our integral would be
Think it's no solution might be wrong though
Answer:
10
Step-by-step explanation:
The given is a special right triangle with angle measures as follows:
45-45-90
The side lengths for this special right triangle are represented as follows:
a (the side length that sees angle measure 45)
a (the side length that sees angle measure 90)
İn the image we can see that one of the side length that sees angle measure 45 is 10
so c, the side length that sees angle measure 90 (hypotenuse),
is equal to
10
