x²+2xsin(xy)+1=0

Simon Bridge · Oct 31, 2011

You mean - what is the graph of the function?

the plot of y(x) vs x will be an arcsine. solve for y.

I mean what is the shape of the graph plotted for the given equation

Simon Bridge · Oct 31, 2011

well then: the plot of y(x) vs x will be an arcsine shape.

Are you having trouble solving for y?
(If so - make sin(xy) the subject and take the arcsine of both sides.)
... which kinda restricts allowed values of x doesn't it.

What you need are turning points, intercepts, and asymptotes - how would you normally find them?

note: this sort of function tends to come up in the context of integrating factors.
