Using the CAS (Computer Algebra System) Mode

u trigToExp (trigToE)

Function: Transforms a trigonometric or hyperbolic function to an exponential function.

Syntax: trigToExp( Exp [ ) ]

Example To convert cos(iX) to an exponential function

1(TRNS)f(TRIG)d(trigToE)c!a(i)vw

u expToTrig (expToT)

Function: Converts an exponential function to a trigonometric or hyperbolic function.

Syntax: expToTrig( Exp [ ) ]

Example To convert e

to a trigonometric function

1(TRNS)f(TRIG)e(expToT)

!I(e

)(!a(i)vw cos(X) + sin(X) • i

u simplify (smplfy)

Function: Simplifies an expression.

Syntax: simplify( {Exp/Eq/Ineq} [ ) ]

Example To simplify 2X + 3Y – X + 3 = Y + X – 3Y + 3 – X

1(TRNS)g(smplfy)ca+(X)+da-(Y)

-a+(X)+d!.(=)a-(Y)

+a+(X)-da-(Y)+d-

a+(X)w

X + 3Y + 3 = –2Y + 3

+ e
