Question
please help me out with the question below thanks.

find the area of the region bounded by the hyperbola
9x^2 - 4y^2 = 36
and the line x = 3

Answer
Let's substitute y=0 into the hyperbola equation, this will give us the point of intersect
of the hyperbola with x-axis :
9*x²-0=36
x²=4
x=±2
Now, let's write the hyperbola in different form :
9x²-4y²=36  -> 4y²=9x²-36 -> 2y=√9√(x²-4) -> y=⅔√(x²-4).

Now, the area will be from x=2 to x=3 . Therefore :
  3
A=∫⅔√(x²-4) dx .
2


I will leave the rest of the calculation for you as an exercise .
