(2) On définit de même la dérivée `a droite que l'on note fd(x0). on applique le théor`eme pour la fonction log sur l'intervalle [x
Once we get the x2 by itself inside the log we may apply the Power Rule with u = x and w = 2 and simplify. log0.1(10x2) = log0.1(10) + log0.1(x2). Product Rule.
S&Z . & .
them one is called partial derivative of z(x y) with respect to x denoted by one of the symbols *(i) u = (tan–1a) [log(x2 + y2)] + btan–1(y/x)

(ii) The function y = f (x) is said to be differentiable in the closed interval [a b] The derivative of logx. w.r.t.
An equation involving derivative (derivatives) of the dependent variable with log x. Example 18 A solution of the differential equation. 2.
Logarithme et Exponentielle : eln x = ln(ex) = x e−x = 1/ex. √ex = ex/2. (ex) y. = exy lim x→−∞ ex = 0 lim x→+∞ ... R`egles de dérivation.
1. If log x2 – y2. = a then x2 + y2. Solution : Take y /x = k → y = k x. → dy/dx = k. → dy/dx = y / x The derivative of an even function is always.
