u tExpand
Function: Employs the sum and difference formulas to expand a trigonometric function.
Syntax: tExpand(Exp/Eq/Ineq/List/Mat [ ) ]
• Ineq (inequality) includes the "≠" (not equal to) relational operator.
Example: To expand sin (a + b)
Menu Item: [Action][Transformation][tExpand]
u tCollect
Function: Employs the product to sum formulas to transform the product of a trigonometric
function into an expression in the sum form.
Syntax: tCollect (Exp/Eq/Ineq/List/Mat [ ) ]
• Ineq (inequality) includes the "≠" (not equal to) relational operator.
Example: To transform cos(a) × cos(b) into an expression in the sum form
Menu Item: [Action][Transformation][tCollect]
u expToTrig
Function: Transforms an exponent into a trigonometric or hyperbolic function.
Syntax: expToTrig (Exp/Eq/Ineq/List/Mat [ ) ]
• Ineq (inequality) includes the "≠" (not equal to) relational operator.
Example: To transform
Menu Item: [Action][Transformation][expToTrig]
u trigToExp
Function: Transforms a trigonometric or hyperbolic function into exponential form.
Syntax: trigToExp (Exp/Eq/Ineq/List/Mat [ ) ]
• Ineq (inequality) includes the "≠" (not equal to) relational operator.
Example: To transform cosh
Menu Item: [Action][Transformation][trigToExp]
u toFrac
Function: Transforms a decimal value into its equivalent fraction value.
Syntax: toFrac (Exp/Eq/Ineq/List/Mat [ ) ]
• Ineq (inequality) includes the "≠" (not equal to) relational operator.
Example: To transform 5.28 into its equivalent fraction value
Menu Item: [Action][Transformation][toFrac]
