Study Notes
Calculus is a branch of mathematics dealing with change, motion, and optimization. It was developed independently by Sir Isaac Newton and Gottfried Leibniz in the late 17th century. There are two main branches of calculus: differential calculus, which focuses on finding rates of change, and integral calculus, which deals with accumulation of quantities.
Limits
Limits are used to find values of functions when the inputs approach certain values. They allow us to evaluate functions at points where they may not be defined. The notation for limits is (lim_{x \to a} f(x)).
Examples of Limit Calculations
The limit of a function at a certain point gives us the value of that function at that point. For example, the limit of (f(x) = x^2) as (x) approaches 2 is 4, since (f(2) = 4).
Derivatives
Derivatives are used to find the rate of change of a function with respect to a variable. They represent the slope of the tangent line to the function at a certain point. The notation for derivatives is (f'(x)) or (df/dx).
Rules of Derivatives
There are several rules for calculating the derivatives of functions:
Power Rule
If (f(x) = x^n), then (f'(x) = nx^{n-1}).
Sum Rule
If (f(x) = g(x) + h(x)), then (f'(x) = g'(x) + h'(x)).
Product Rule
If (f(x) = g(x)h(x)), then (f'(x) = g'(x)h(x) + g(x)h'(x)).
Quotient Rule
If (f(x) = g(x)/h(x)), then (f'(x) = (g'(x)h(x) - g(x)h'(x))/h^2(x)).
Differentiation Rules
Differentiation rules are used to find the derivatives of functions. They provide a systematic way to calculate the derivatives of a wide variety of functions.
Power Rule
The power rule states that the derivative of a function (f(x) = x^n) is (f'(x) = nx^{n-1}).
Sum Rule
The sum rule states that the derivative of a sum of functions (f(x) = g(x) + h(x)) is the sum of their derivatives (f'(x) = g'(x) + h'(x)).
Product Rule
The product rule states that the derivative of a product of functions (f(x) = g(x)h(x)) is the sum of (g'(x)h(x)) and (g(x)h'(x)).
Quotient Rule
The quotient rule states that the derivative of a quotient of functions (f(x) = g(x)/h(x)) is ((g'(x)h(x) - g(x)h'(x))/h^2(x)).
Calculus is a powerful tool used in physics, engineering, economics, and many other fields. Understanding its concepts, such as limits, derivatives, and differentiation rules, allows us to model complex systems and solve problems involving change and optimization.
