The two main applications that we'll be looking at in this chapter are using derivatives to determine information about graphs of functions and optimization problems. A relative maximum of a function is an output that is greater than the outputs next to it. A tangent is a line drawn to a curve that will only meet the curve at a single location and its slope is equivalent to the derivative of the curve at that point. Applications of Derivatives in maths are applied in many circumstances like calculating the slope of the curve, determining the maxima or minima of a function, obtaining the equation of a tangent and normal to a curve, and also the inflection points. Find an equation that relates your variables. A problem that requires you to find a function \( y \) that satisfies the differential equation \[ \frac{dy}{dx} = f(x) \] together with the initial condition of \[ y(x_{0}) = y_{0}.
