Best ResponseYou've already chosen the best response.1Take log of y and then differentiate... (dy/dx) at x=1 will give the slope of the tangent...

Best ResponseYou've already chosen the best response.0when you say dy/dx at x=1 do you mean to plug in 1 for all x after i get the derivative of the equation?

Best ResponseYou've already chosen the best response.1you can also find y at x=1... Thus you know the slope and one point in the line which will help you to find the equation...

Best ResponseYou've already chosen the best response.1taking log of p log(p)=x^2*log(x) then differentiate (1/p)dp/dx=x^2/x+2xlog(x) dp/dx=p[x+2xlog(x)] dp/dx=x^(x^2)*[x+2xlog(x)]
