Chapter 1: Q30MP (page 1)

Short Answer

Expert verified

T=1.2 sec

The period represents the time taken by an individual for one breath cycle that is the time taken by the heart to beat once.

Step by step solution

01

The given function is

pt=-20cos300t+100

Wherep is the blood pressure in millimeters and t is the time in seconds.

02

We have to find the period of the function

(a).

If y=Acoskx-d+c

Then period T=360°k

On comparing we get k=300°

So, the period of the function is:

T=360°k=360°300=360°300=1.2

So, we get T=1.2 sec

The period represents the time taken by an individual for one breath cycle that is the time taken by the heart to beat once

By the method used to obtain (12.5)[which is the series(13.1)below], verify each of the other series (13.2)to (13.5)below.

Use power series to evaluate the function at the given point. Compare with computer results, using the computer to find the series, and also to do the problem without series. Resolve any disagreement in results (see Example 1).esinx-1x3In(1+x3ex)atx=0.00035.

Test the following series for convergence

cos(ex-1)

Evaluate the following indeterminate forms by using L’Hopital’s rule and check your results by computer. (Note that Maclaurin series would not be useful here because xdoes not tend to zero, or because a function (In x, for example) is not expandable in a Maclaurin series.
