Best ResponseYou've already chosen the best response.0btw here is graph of curve http://www.wolframalpha.com/input/?i=y+%2B+cos%28y%29+%3D+x%2B1+%2C+from+x%3D0+to+2pi%2C+from+y%3D0+to+2pi

Best ResponseYou've already chosen the best response.0oh ok i think i see why u canceled the variables on the right side of the equation :)

Best ResponseYou've already chosen the best response.0so 1/(1siny) is part a.)?

Best ResponseYou've already chosen the best response.1the x didnt cancel the derivative of x+1 = just 1 since its wrt x

Best ResponseYou've already chosen the best response.1and yes thats your part a

Best ResponseYou've already chosen the best response.1so vertical asymptotes is what makes the bottom of a fraction = 0

Goten77

Best ResponseYou've already chosen the best response.1but we need the vertical asymptote so we needa find the x value so we put the equation in the form of x = #

Goten77

Best ResponseYou've already chosen the best response.1so now we use the original equation and use that y value to solve for the x

Best ResponseYou've already chosen the best response.1so the vertical graph is x= (pi  2)/ 2

Best ResponseYou've already chosen the best response.1i got 1=siny because it was 1st 1siny= 0 i just moved it over

Best ResponseYou've already chosen the best response.0so part b.) is (pi 2)/2

Best ResponseYou've already chosen the best response.1this is basically the quotient rule + implicint differentation + production rule + chain rule THEN use that negative .... you dont have to simplify unless ur told to.. which i dont think u can
