So we get log (y) = x log (2) 3) Differentiate both sides with respect to x LHS log (y) => (1/y) (dy/dx) partial differentiation hence we multiply (1/y) by dy/dx RHS x log (2) => log (2) log (2) is a constant so x dissapears So we get (1/y) (dy/dx) = log (2) 4) We want to find dy/dx, which isY = X Dy/dx = This problem has been solved!A first order Differential Equation is Homogeneous when it can be in this form dy dx = F ( y x ) We can solve it using Separation of Variables but first we create a new variable v = y x v = y x which is also y = vx And dy dx = d (vx) dx = v dx dx x dv dx (by the Product Rule) Which can be simplified to dy dx = v x dv dx

Answer to Find dy/dx by implicit differentiation \sqrt{xy} = 5 x^{2}y By signing up, you'll get thousands of stepbystep solutions to yourDy dx = f0(x) However, we can treat dy/dx as a fraction and factor out the dx dy = f0(x)dx where dy and dx are called differentialsIfdy/dx can be interpreted as "the slope of a function", then dy is the "rise" and dx is the "run" Another way of looking at it is as follows • dy = the change in y • dx = the change in xSolve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more
