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
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).
u u u u u Complex 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:
e iX
6(g)5(CPLX)1(expTo)
!e(3(i)v)w
u u u u u Complex 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
