WebThe derivative of y is dy, of x is dx. So that was main mistake. Note: It is easier to do these problems with the y' notation instead of the dx notation. Here is how to solve the problem: cos²(xy)=x+y 2cos(xy) (-sin(xy)) (xdy + y dx) = dx + dy −2cos(xy) sin(xy) (xdy + y dx) = dx + dy −2x cos(xy) sin(xy) dy −2y cos(xy) sin(xy) dx = dx + dy WebThis same result would be obtained by solving for y so that y = x 2 + 1, from which dy/dx = 2x. In this example it is easier to first solve for y and then differentiate, but this will not always be the case. Example 1. Find the slope of the tangent line to the graph of the equation xy - x = 1 at that point on the graph whose first coordinate is ...
