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