Derivative test increasing decreasing

WebFeb 26, 2024 · When the first derivative tells us whether the given function is increasing or decreasing, the second derivative tells us if the first derivative is increasing or decreasing. The second derivative test is also applied to locate the local maxima and local minima of a function with one variable, two variables and more under specific conditions. WebApr 11, 2024 · In this research, amphiphilic derivatives of kappa carrageenan (KC) were synthesized by hydrophobic modification with an alkyl halide (1-Octyl chloride).
