() Parentheses Used to group numbers or variables together in an expression. {} Braces Used to group sets of numbers or variables together. [] Brackets Used to group sets of numbers or variables together. ∑ Summation Used to represent the sum of a set of numbers. ∏ Product Used to represent the product of a set of numbers. ∫ Integral Used to represent the area under a curve in calculus.
Trigonometry Symbols
Symbol Name Explanation sin Sine The ratio of the length of the opposite side to the hypotenuse. cos Cosine The ratio of the length of the adjacent side to the hypotenuse. tan Tangent The ratio of the length of the opposite side to the adjacent side. cot Cotangent The ratio of the length of the adjacent side to the opposite side. sec Secant The reciprocal of the cosine. csc Cosecant The reciprocal of the sine.
Calculus Symbols
Symbol Name Explanation ∂ Partial derivative The derivative of a function with respect to one of its variables, holding the other variables constant. ∇ Nabla A vector operator used in vector calculus to represent various operations, such as gradient, divergence, and curl. ∞ Infinity Indicates a value that is infinitely large. lim Limit Indicates the value that a function approaches as its input approaches a certain value. d/dx Derivative Indicates the rate at which a function is changing with respect to its input.
Set Theory Symbols
Symbol Name Explanation ∈ Element of Used to indicate that an element belongs to a set. ∉ Not element of Used to indicate that an element does not belong to a set. ⊂ Subset Used to indicate that one set is a subset of another. ⊆ Subset or equal to Used to indicate that one set is a subset or equal to another. ∩ Intersection Used to indicate the set of elements that are in both sets. ∪ Union Used to indicate the set of elements that are in either or both sets. ∅ Empty set A set with no elements.
Logic Symbols
Symbol Name Explanation ∧ Conjunction Used to represent logical “and”. ∨ Disjunction Used to represent logical “or”. ¬ Negation Used to represent logical “not”. → Implication Used to represent logical “if-then”. ↔ Bi-implication Used to represent logical “if and only if”. ⊕ Exclusive or Used to represent logical “exclusive or”. ⊤ Tautology A statement that is always true. ⊥ Contradiction A statement that is always false.
