Question Number 66827 by mr W last updated on 20/Aug/19

Commented by mr W last updated on 20/Aug/19

the graph above shows the equation  ((ln (x+(√(1+x^2 ))))/(√(1+x^2 )))=((ln (y+(√(1+y^2 ))))/(√(1+y^2 )))    it contains in fact two curves:  curve 1: y=x which always fulfills  the equation  curve 2: y=???    can you find the function for curve 2  in form of y=f(x)?  can you find the intersection point  of both curves? i mean with exact  values?

Sir ,is there any process of decomposing  such functions ?

I don′t know, sir.  That′s also my question.  A famous example is x^y =y^x .

Idontknow,sir.Thatsalsomyquestion.Afamousexampleisxy=yx.
