Drawing graph of functions HELP

AI Thread Summary
The discussion revolves around the difficulties of graphing the function y=fr(x) where fr(x)=1.5/sin(x) within the domain (0, 1/2π). The user expresses a lack of understanding in creating a table of values for plotting the graph and mentions issues with their calculator outputting a constant line. Other participants suggest that using a range of different x values between 0 and 1/2π is essential for generating accurate y values. They also emphasize the importance of ensuring the calculator is set to radian mode to avoid errors. The conversation highlights the need for a step-by-step approach to effectively graph functions.

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.
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
