Short Answer

Expert verified

The improper integral on [1,∞)diverges.

∫1∞x-0.99dx=∞

Step by step solution

01

Step 1. Given information.

The given improper integral is following.

∫1∞x-0.99dx

02

Step 2. Value of integral.

Write the integral in the proper form of ∫1∞1xpdx

∫1∞1xpdx=∫1∞x-0.99dx∫1∞1xpdx=∫1∞1x0.99dxp=0.99&0.99<1

The Fundamental Theorem of Calculus tells us that the improper integral on [1,∞)diverges.

∫1∞x-0.99dx=limb→∞∫1bx-0.99dx=limb→∞100x0.011b=limb→∞100b0.01-100=∞
