Is that a comma or a y' at the end of that first equation?

vishweshshrimali5 · Answer

it is a coma

anonymous · Answer

So I guess you integrate the first equation, use y(0) = 0 to find the constant, and substitute into the equation to find the answer.

Give me a minute to try this

I'm finding it really difficult. There doesn't seem to be a good way to simplify it: http://www.wolframalpha.com/input/?i=%28%28cosy+-+2sinx+-+6%29cosx%29%2F%28%28sinx+%2B+4cosy+%2B+2%29siny%29

vishweshshrimali5 · Answer

so what should we do then........

anonymous · Answer

Hmm. I'll keep looking at it and I'll let you know if I come up with anything.

vishweshshrimali5 · Answer

ok thanks

anonymous · Answer

Actually, we're just taking the integral with respect to x right? So I couldn't come up with it myself but wolfram alpha produces this: http://www.wolframalpha.com/input/?i=integral+with+respect+to+x%3A+%28%28cosy+-+2sinx+-+6%29cosx%29%2F%28%28sinx+%2B+4cosy+%2B+2%29siny%29

anonymous · Answer

So substitute (x,y) = (0,0) for the constant and then substitute Pi/2 into the equation.

vishweshshrimali5 · Answer

but putting x=y=0 in the eq. gives infinite value

anonymous · Answer

I don't know then. It's a really tough question in my opinion.

vishweshshrimali5 · Answer

please try to give me some hint so that I can proceed.......

anonymous · Answer

I really wish I could but you're probably just as good or better at it than I am.

vishweshshrimali5 · Answer

no not at all don't even think that
