ALGBR Mode Commands 20 - 3

Syntax: sumSeq ({<value>, <value>, ...} [,<variable>] [)]

• A default variable of X is used when specification of a variable is skipped.

Example To obtain an expression that expresses the sum up to the nth

term when terms 1 through 4 are the following sequence of

values: {23, 30, 37, 45}

6(g)4(PTS

)2(smSq)

!{cd,da,dh

,ef!},aNw

• If List 1 = {23, 30, 37, 45}, the same result can be obtained by inputting the

following: sumSeq(List 1, N).

uComplex Exponential-to-Trigonometric Transformation ——

(expTo)

This command transforms an exponential function whose exponent includes an

imaginary number to a trigonometric function.

Syntax: expToTrig (<expression>[)]

Example To transform the following function to a trigonometric function:

6(g)5(CPLX)1(expTo)

!e(3(i)v)w cos(X) + i • sin(X)

uComplex Trigonometric-to-Exponential Transformation —— (trgTo)

This command transforms a trigonometric function whose argument is an

imaginary number to an exponential function.

Syntax: trigToExp (<expression>[)]

Example To transform the following function to an exponential function:

cos iX

6(g)5(CPLX)2(trgTo)

c(3(i)v)w
