Constructors

Cos(Expression operand, {int n = 1})
Creates an instance of the Csc class with the given operand and n.

Properties

hashCode → int

no setterinherited
n → int
The power to which csc is raised.
final
operand → Expression
finalinherited
periodicity → double
Returns the periodicity of the csc function raised to the power of n.
no setter
runtimeType → Type
A representation of the runtime type of the object.

Methods

definiteIntegral(String variable, num a, num b) → dynamic

Available on Expression, provided by the SymbolicCalculusExtension extension

Computes the definite integral from a to b.
depth() → int
Calculate the depth of the expression tree.
inherited
differentiate([Variable? v]) → Expression
Differentiates the expression with respect to a variable.
override
evaluate([dynamic arg]) → dynamic
Evaluates the expression for a given value of x.
override
expand() → Expression
Expands the expression, if applicable, and returns a new expanded expression.
override
getVariables() → Set<Variable>
Retrieves the base variables present in the expression, effectively decomposing composite variables into their constituent parts. For instance, for an expression containing x^2, it returns x, and for x*y, it returns both x and y.
inherited
getVariableTerms() → Set<Variable>
Retrieves all variables present in the expression, including composite variables like x^2 or x*y.
inherited
integrate() → Expression
Integrates the expression with respect to a variable.
override
isIndeterminate(dynamic x) → bool
inherited
isInfinity(dynamic x) → bool
inherited
isPoly([bool strict = false]) → bool
Checks if the expression is a polynomial.
inherited
limitAt(String variable, num value, {String direction = 'both'}) → dynamic

Available on Expression, provided by the SymbolicCalculusExtension extension

Computes the limit as a variable approaches a value.
maclaurin(String variable, int order) → Expression

Available on Expression, provided by the SymbolicCalculusExtension extension

Computes the Maclaurin series expansion.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
partialD(String variable) → Expression

Available on Expression, provided by the SymbolicCalculusExtension extension

Computes the partial derivative with respect to a variable.
simplify() → Expression
Simplifies the expression, if possible, and returns a new simplified expression.
inherited
simplifyBasic() → Expression
Performs basic simplification (arithmetic, combining like terms).
override
size() → int
Compute the size of the expression based on the number of nodes in its tree.
inherited
substitute(Expression oldExpr, Expression newExpr) → Expression
Replace a sub-expression or a variable with another expression.
inherited
taylor(String variable, num point, int order) → Expression

Available on Expression, provided by the SymbolicCalculusExtension extension

Computes the Taylor series expansion around a point.
toString() → String
Returns the string representation of the expression.
override
