Using the Action Menu

utCollect

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]

uexpToTrig

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 eix into a trigonometric function (Radian mode) Menu Item: [Action][Transformation][expToTrig]

utrigToExp

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 coshx into exponential form

Menu Item: [Action][Transformation][trigToExp]

udms

Function: Transforms a DMS format value into its equivalent degrees-only value.

Syntax: dms (Exp/List-1 [,Exp/List-2][,Exp/List-3] [ ) ]

Example: To transform (3, 5, 6) (= 3q 5’ 6”) into its equivalent degrees-only value

Menu Item: [Action][Transformation][dms]

• Zero is the default when you omit [,Exp/List-2] or [,Exp/List-3][ ) ].
