I can't choose between these two. Please help me, /sci/. Which one should I buy? I study electrical engineering. Thank you very much.

That Casio is the comfiest thing in my life

>>

>>7589084

It hardly matters

I use the second type

>>

>>7589084

ti36x is more numerically oriented

>>

>>7589084

I have the ti 36 pro, the buttons are cheap and shitty like most Texas instrument equipment but it gets the job done.

>>

>>7589084

Casio

>>

Are there any differences between the TI-36X Pro and the FX-115ES Plus in performing complex number calculations?

>>

the casio is better.

source: i'm in EE too and ive tried both

>>

How exactly is it better?

>>

>>7589169

CASIO FX-115ES PLUS 12.97 (C)

CANON F-792SGA 15.14 (N)

SHARP EL-W516B 17.30 (S)

TI-36X PRO 19.97 (T)

COMPLEX NUMBERS

C,N exact radical form

S can only be stored in M, division can not be entered as fraction

T does not require COMPLEX mode, must scroll to see all digits

STATISTICS/REGRESSION

C,N,S quadratic regression calculates both x1' and x2'

N calculates mode and range

S does not calculate min Q1 med Q3 max, easy to RCL vars and to calc x' & y'

T cubic regression, 2-Var Stats menu includes x'(y) and y'(x) for linear reg

BASE NUMBERS

N binary numbers displayed in blocks of 4-digits

S can not + - * / different bases (no b o d h prefix/suffix), PEN (base 5)

T calculates LOGIC nand

POLYNOMIAL EQUATIONS

C,N 2nd degree (quadratic formula) exact radical form

C,T calculates vertex of parabola (S functions can be programmed)

N 4th degree polynomial (includes complex roots)

T gives option of storing results in variable memories

POLYNOMIAL INEQUALITY

C,N exact radical form of 2nd degree polynomial

N 4th degree polynomial

S,T no inequality

SYSTEMS OF EQUATIONS

C Infinite Solution & No Solution enunciators

N solves 4X4 system

S 4X4 matrices can solve 4X4 system using Inv(4X4)X(4X1)

S calculates determinant of Cramer-method denominator

T gives results of 2-equation 3-variable system in terms of z

FUNCTION TABLE

C 2 functions, f(x) & g(x) calculated side-by-side

N 1 function, f(x)

S no function table

T 1 function, Auto scrolls up or down from initial value of x

T x=? inputs user values for x (Auto is disabled)

MATRIX

C,T ref & reduced-ref

N, S 4X4 matrices, 4th matrix (matrix D)

N calculates adjoint matrix

S fill, cumulative, augment, random, matrix>list

N,S,T identity matrix

LIST

C,N no list mode

S 4th list (list 4), square, cube, reciprocal can be applied to lists

S sort A&D, fill, cum, difference list, aug, abs (sqrt of sqr-sum)

S min max mean median sum product SD variance, list>matrix

T list formulas accept all calculator functions and real numbers

UNIQUE FEATURES

C VERIFY checks results of number & algebra expressions

C PreAns (PreAns + Ans generates Fibonacci Sequence)

C recurring decimal (gives ALL 60 digits of 1/61)

C remainder division (N,T have mod function)

C old FX-115MS SOLVE did not require comma-variable to select

C old FX-115MS % could calculate percent + or - & percent change

C,N multi-statements (displays all 6 answers of ambiguous case with =)

C old FX-115MS could COPY multi-statements

C,N independent memory M (generates & totals A or G sequence with =)

C,N Square Root & Ans require single keystroke (not Shift 2nd 2nd-F ALPHA)

T Multi-Tap Keys cycle through multiple functions when pressed (! nCr nPr)

T recall (RECALL VAR) displays menu of all 8 memory variables & stored values

T memory X can be accessed with a single keystroke

T set-op & op Stored Operations (up to 44 characters) applied to ANS or entry

T can not clear old data with single keystroke (matrix, vector, poly, sys)

T no cube, cube-root, independent-memory (M)

FRACTION DECIMAL CONVERSIONS

C S<>D (improper>repeating>decimal), shift a b/c<>d/c (mixed)

N F<>D (improper<>decimal), shift a b/c<>d/c (mixed)

S CHANGE (mixed number>improper>decimal), no shift, no menu

T f<>d (decimal<>improper), math menu 1:n/d<>Un/d (mixed)

T each conversion regarded as new calculation & bumps display upward

EXPRESSION EVALUATION: C,N CALC; S MATH, ALGB; T expr-eval

S does not accept complex numbers

INTERNAL DIGITS: C 15, N 20, S 14, T 13

CONSTANTS: C 40 (on cover), N 79, S 52, T 20

CONVERSIONS: C 40 (on cover), N 172, S 44, T 40

KEYSTROKES REQUIRED FOR SELECTED PROBLEMS

dms + dms = dms: C,N,S 8; T 35

polar rectangular conversion: C,N 15; S 3; T 18

linear regression & x'(y): C,N 15; S 9; T 23

braking test problem & y'(x): C,N 19; S 13; T 26

base numbers: C,N neg(FF) 8; S -FF 4; T 2's(FF) 16

TI-36X is better.

>>

If these are imposed by the department, never buy ti and always buy casio.

Else, hp50g

>>

>>7589084

My math proffesor got mad at me for having the ti36 because it has integration and derivatives on it. Now I guess I cant use that calculator anymore. Gonna have to buy another one. God damnit you know how many calculators I've had to buy?
