 Here are some common symbols used in calculus and analysis:

 

Basic Operations:

• “+” : Addition

• “×” : Multiplication
• “÷” : Division

Powers and Exponents:

• “^” : Exponentiation (e.g., x^2 means x raised to the power of 2)
• “√” : Square Root (e.g., √x represents the square root of x)
• “∛” : Cube Root (e.g., ∛x represents the cube root of x)

Limits:

• “lim” : Limit (e.g., lim(x → a) f(x) represents the limit of f(x) as x approaches a)

Set Notation:

• “∈” : Element of (e.g., x ∈ A means x is an element of set A)
• “∉” : Not an element of (e.g., x ∉ A means x is not an element of set A)
• “⊆” : Subset of (e.g., A ⊆ B means set A is a subset of set B)

Other Notations:
