We must find dy/dx at x = 1 Assume y is a function of x, y = y(x) The relation now is xy(x) x = 1 Hence, and by the extended power rule, Substituting these results into Formula (2), we obtain We solve this equation for dy/dx Be careful!Dy dx = −x/y dy dx = −3/4 And for bonus, the equation for the tangent line is y = −3/4 x 25/4 Another Example Sometimes the implicit way works where the explicit way is hard or impossible Example 10x 4 − 18xy 2 10y 3 = 48 How do we solve for y?
