Module 12
Que 1 Determine the area of the region between the two curves by integrating over
the y-axis.
? = ?2, ??? ? = 9
Answer:
First let’s find out intersection points.
? = ?2, ??? ? = 9
?2 = 9 ⇒ ? = ±3
So, inter
section points are (9, −3) and (9,3)
Now,
???? = ∫ [?(?) − ?(?)]??

Que 2. Graph the equations and shade the area of the region between the curves.
Determine its area by integrating over the x-axis.
? = ??, ? = ?2?−1, ??? ? = 0
Answer:
? = ?? , ? = ?2?−1
⇒ ?? = ?2?−1
? = 1
? = ?? ? = ?2?−1
???? = ∫ (

Answer:
???? = ∫ (? − ?−?)??

Que 4. Graph the equations and shade the area of the region between the curves. If
necessary, break the region into subregions to determine its entire area.
? = ?2 + 9, ??? ? = 10 + 2?, ???? ? = [−1,3]
Answer:
First let’s find out intersection point,
? = ?2 + 9, ??? ? = 10 + 2?
?2 + 9 = 10 + 2?
?2 − 2? − 1 = 0
? = 1 ± √2
So,
???? = ∫ (?2 + 9 − 10 − 2?)
