I have no idea how to use mathematica and my prof ended up telling us to get solve this diffequ. using it. dy/dx=y-sinx.

OpenStudy (anonymous):

Do you have to use mathematica?

OpenStudy (anonymous):

yeah...He wants us to generate the solution curves for it.

OpenStudy (bahrom7893):

Type this inside the mathematica notebook: DSolve[y'[x] == y[x] - Sin[x], y[x], x]

Type this inside the mathematica notebook: DSolve[y'[x] == y[x] - Sin[x], y[x], x]

OpenStudy (anonymous):

x Cos[x] + Sin[x] Out[1]= {{y[x] -> E C[1] + ---------------}} 2 it showed something like this; how can I get the plot of the solution curve?

OpenStudy (bahrom7893):

im researching it lol, luckily i had mathematica, never used it before..

do you want me to send you the mathematica notebook?

OpenStudy (anonymous):

sure, it would be a great help, but this graph should cover the region x=-3 to x=3 and y=-3 to y=2

OpenStudy (anonymous):

I am very grateful to you. I definitely need that mathematica notebook

OpenStudy (bahrom7893):

sorry, i tried about 20 different ways of limiting y.. I have no idea how to do that, email me at bahrom.cfo@gmail.com the best I can do is send you the notebook, I only managed to limit x values, sorry =[

OpenStudy (anonymous):

but how did it look like ...may be u got it right can u send it to me , whatever u got.... vinita.verma90@gmail.com
