Drawing graph of functions HELP

Click For Summary

Homework Help Overview

The discussion revolves around the challenges of graphing the function y=fr(x), where fr(x)=1.5/sin(x) within the domain (0, 1/2π). The original poster expresses difficulty in creating a table of values necessary for plotting the graph and seeks guidance on the process.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to use a calculator to generate values for the function but encounters issues with obtaining the correct output. Participants inquire about the specific values being input and the calculator's mode.

Discussion Status

The discussion is ongoing, with participants providing hints and prompting the original poster to consider using a range of x values rather than a single value. There is no explicit consensus yet on the best approach to take.

Contextual Notes

The original poster mentions a prior understanding of what the graph should look like but struggles with the practical aspects of generating data points. There may be assumptions about the use of the calculator that are being questioned.

drawing graph of functions...HELP!

ok, i am going to admit i am TERRIBLE when it comes to drawing graphs of functions. I have no idea what i am doing and kind of need a step by step approach. I really want to learn the best way of doing this as its now a big obstacle in my course.

The question i have is basically plot a graph of the function y=fr(x)
Im told that fr(x)=1.5/sin(x)
the domain is (0,1/2*\pi)

I already have an answer of what the graph SHOULD look like but am having trouble getting together a table of values to draw it with for myself. I have tried on my calculator but it keeps giving me a parallel line of y=1.5 (if that makes sense)
i know i must be putting it in wrong

HELP...!

What values are you putting in for x? Is your calculator in radian mode?
 


ive been putting in 1/2*pi for x...yes it is in radians
 


Well, if you always put in the same x, you will always get out the same y!

Put in a number of different values for x between 0 and (1/2)\pi.
