Kalkulus Diferensial dan Limit

Study Notes

Differential Calculus

Differential calculus deals with rates of change of functions.
It's concerned with instantaneous rates, unlike average rates considered in other areas of mathematics.
The central concept is the derivative, which measures the slope of the tangent line to a curve at a specific point.
The derivative of a function at a point represents the instantaneous rate of change of the function at that point.
Different notations for the derivative include f'(x), dy/dx, and d/dx (f(x)).
Basic rules for differentiating functions include the power rule, constant multiple rule, sum/difference rule, product rule, and quotient rule.
Using these rules, complicated functions can be differentiated step by step.

Limits and Continuity

Limits describe the behavior of a function as the input approaches a specific value.
A limit exists if the function approaches a finite value as the input approaches the limit point.
Continuity at a point means that the function's value at that point is equal to its limit as the input approaches that point.
A function is continuous over an interval if it's continuous at every point within that interval.
Techniques for evaluating limits include direct substitution, factoring, rationalizing, and L'Hôpital's rule for indeterminate forms.
Discontinuity can appear as a jump, removable discontinuity, or infinite discontinuity.
Understanding limits is fundamental to understanding derivatives.

Implicit Differentiation

Implicit differentiation allows for finding the derivative of a function implicitly defined by an equation.
In this, you differentiate the equation directly with respect to x, treating y as a function of x (not a variable) and implicit differentiation will get you dy/dx.

Applications of Calculus

Calculus finds applications in numerous fields, from physics and engineering to economics and finance.
Optimization problems (finding maximum and minimum values) are a common application.
In physics, it's used in problems involving motion and forces.
In economics, optimization problems might entail maximizing profit or minimizing cost.
Calculus aids in modelling complex systems and resolving real-world challenges through mathematical analysis.
Understanding rates of change is fundamental for many analyses in numerous fields.

Integral Calculus

Integral calculus is the inverse operation of differential calculus.
It deals with accumulation of quantities over an interval.
The fundamental theorem of calculus connects the concepts of differentiation and integration.
Indefinite integrals are general solutions to differentiation problems that contain an arbitrary constant.
Definite integrals have definite bounds yielding the exact accumulated quantity within a particular interval.
Techniques for evaluating integrals include substitution, integration by parts, partial fractions, tables of integrals, and numerical methods.
Applying integration to find areas under curves is an important application.
Integral calculus is also used to find volumes of solids of revolution and volumes of solids with known cross-sections.
