Question

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.

Answer 1

Do you have to use mathematica?

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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?

Answer 6

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

Answer 7

i think i almost got it..

Answer 8

WOOT I GOT IT!! LOL

Answer 9

where do u want me to show u the screen?

Answer 12

do you want me to send you the mathematica notebook?

Answer 13

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

Answer 14

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

Answer 15

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 =[

Answer 16

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
