Chapter 1: Differential Calculus




Basic concepts and rules




Differential calculus is the study of rates of change of functions and their graphs. The main concept of differential calculus is the derivative, which measures the instantaneous rate of change of a function at a given point. The derivative of a function f(x) is denoted by f'(x) or dy/dx, where y = f(x).


The derivative of a function can be interpreted as the slope of the tangent line to the graph of the function at a given point. The derivative can also be used to find the rate of change of various quantities, such as velocity, acceleration, force, temperature, etc.


To find the derivative of a function, we can use various rules and formulas, such as:



  • The power rule: If f(x) = x^n, then f'(x) = nx^(n-1).



  • The sum rule: If f(x) = g(x) + h(x), then f'(x) = g'(x) + h'(x).



  • The product rule: If f(x) = g(x)h(x), then f'(x) = g'(x)h(x) + g(x)h'(x).



  • The quotient rule: If f(x) = g(x)/h(x), then f'(x) = (g'(x)h(x) - g(x)h'(x))/[h(x)]^2.



  • The chain rule: If f(x) = g(h(x)), then f'(x) = g'(h(x))h'(x).



Applications of differentiation




Differentiation has many applications in engineering and science, such as:



  • Finding the maximum and minimum values of a function or a quantity.



  • Finding the points of inflection and concavity of a function or a graph.



  • Finding the optimal values of a function or a quantity under certain constraints or conditions.



  • Finding the rates of change of various quantities, such as velocity, acceleration, force, temperature, etc.



  • Finding the linear approximation and error estimation of a function or a quantity near a given point.



  • Finding the sensitivity and elasticity of a function or a quantity with respect to another variable.



Maxima and minima problems




One of the most common applications of differentiation is to find the maximum and minimum values of a function or a quantity. These values are also called extrema or extreme values. There are two types of extrema: global (or absolute) and local (or relative).


A global maximum (or minimum) is the highest (or lowest) value that a function or a quantity can attain in its entire domain. A local maximum (or minimum) is the highest (or lowest) value that a function or a quantity can attain in a certain interval or neighborhood.


To find the extrema of a function or a quantity, we can use the following steps:



  • Find the first derivative of the function or the quantity and set it equal to zero. This will give us the critical points, which are the possible candidates for extrema.



  • Find the second derivative of the function or the quantity and evaluate it at each critical point. This will help us to determine whether the critical point is a maximum, a minimum, or neither.



  • If the second derivative is positive at a critical point, then it is a local minimum. If it is negative, then it is a local maximum. If it is zero, then it is inconclusive and we need to use other methods, such as the first derivative test or the sign test.



  • Compare the values of the function or the quantity at each critical point and at the endpoints (if any). The highest value is the global maximum and the lowest value is the global minimum.



Chapter 2: Integral Calculus




Basic concepts and rules




Applications of integration




Integration has many applications in engineering and science, such as:



  • Finding the area under a curve or between two curves.



  • Finding the volume of a solid of revolution or by cross-sections.



  • Finding the arc length or surface area of a curve or a surface.



  • Finding the work done by a variable force or the center of mass of a system.



  • Finding the average value or the mean value of a function or a quantity.



  • Finding the probability or the expected value of a random variable or an event.



Definite and indefinite integrals




There are two types of integrals: definite and indefinite. A definite integral is an integral that has limits of integration, which specify the interval over which the integration is performed. A definite integral represents the net area under a curve between two points. A definite integral can be evaluated using various methods, such as:



  • The fundamental theorem of calculus: If f(x) is a continuous function on [a,b] and F(x) is an antiderivative of f(x), then f(x)dx from a to b = F(b) - F(a).



  • The substitution rule: If u = g(x) is a differentiable function whose range is an interval I and f is continuous on I, then f(g(x))g'(x)dx = f(u)du.



  • The integration
