is that with X set to 0 to 360

so how can i find the two solutions to the equation? in the peaks?

well now ive graphed it - how can i find the 2 solutions of that equation that are between 0 - 360 degrees?

What are you trying to solve for? Is this the way the question was worded? Can you give me the question exactly as it appears in your book? I don't know how to help you because I can't figure out what it is you solving for

2 solutions between

between 0 and 360degree

Ok, now I see what you need to do. The sin(x) curve has an infinite domain , but comes back to the x axis (where y equals zero)at x = 0 and at x= pi. In the case of this problem, the sine curve is shifted down .06. So it won't = 0 at x=0 or pi, it will be 0 somewhere just larger than 0 and pi. ( I'm guessing probably at .06). As far as from 0 to 2pi ( or in your case 360 deg) you will actually have 3 answers. The solutions are the x values on the curve when y = 0

Does that make sense? Good luck! - Jan 22nd 2009, 08:58 AMADY

You can do this graphically if you own a graphing calculator. However, depending on what model you have, the procedure would be different. And I believe there is a section in this forum devoted to calculator use.

To do this algebraically,

Then to find a approximation of x, find the key on your calculator and calculate what is. - Jan 23rd 2009, 01:08 AMADY
How can there be two answers then? because of where the curve crosses the x axis?
