[Definition 10.2.1] Let f:X\rightarrow \mathbb{R} be a function, and let x_0\in X。 We say that f attains a local maximum at x_0 if and only if there exists a \delta>0 such that the restriction f|X\cap(x_0-\delta,x_0+\delta) of X\cap (x_0-\delta,x_0+\delta) at...

This “new” function gives the slope of the tangent line to the graph of f at the point(x, f(x)), provided that the graph has a tangent line at this point. The process of finding the derivative of a function is called differentiation. f’(x) = lim(Δx—0) [f(x+Δx) - f...
You can also perform differentiation of a vector function with respect to a vector argument. Consider the transformation from Cartesian coordinates(x,y,z)to spherical coordinates(r,λ,φ)as given by x=rcosλcosφ, y=rcosλsinφ, z=rsinλ. ...
Cell death and Differentiation provides an accessible source of up-to-date information for scientists and clinicians. It covers programmed cell death, cell death induced by toxic agents, differentiation and their relation to cell proliferation.
It is well known from elementary calculus that ordinary functions have closed-form formulas for finding the derivative of a given function. Consequently, in differentiating known function, Equation (1) is seldom needed. The geometrical interpretation of the derivative of a function is the slope of ...
