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 [
