Find the area under the curve y = 25/x3 from x = 1 to x = t. Evaluate the area under the curve for t = 10, t = 100, and t = 1000
. t = 10 t = 100 t = 1000 Find the total area under this curve for x ≥ 1.
1 answer:
Answer:
12.375 for t=10, 12.49875 for t=100, 12.49999 for t=1000, 12.5 for
.
Step-by-step explanation:
One way to find the area under the curve
from x = 1 to x = t, is to calculate the next integral
.
For t = 10 we have
.
For t = 100 we have
.
For t = 1000 we have
.
The total area under this curve for
is given by
![lim_{t\to\infty}(-25/2)[t^{-2}-1] = (-25/2)(-1) = 25/2 = 12.5](https://tex.z-dn.net/?f=lim_%7Bt%5Cto%5Cinfty%7D%28-25%2F2%29%5Bt%5E%7B-2%7D-1%5D%20%3D%20%28-25%2F2%29%28-1%29%20%3D%2025%2F2%20%3D%2012.5)
