Using the Action Menu
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
e
ix
into a trigonometric function (Radian mode)
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
x
into exponential form
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]
