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

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
e
ix
into a trigonometric function (Radian mode)

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

dms
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) (= 3
q
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][ ) ].
