How to solve for X?

[MrKHoucem]

i have a el-W506 calculator i have got it all but there is a serious problem when i want to enter a definable memory i do that :

STO + D1 + ALPHA +RCL( to enter X as a variable ) the problem is that i cant add something else it stopes and say : STORED ! and dont let me finish the equation

[1Krje]

can i play games ?

@1Krje yes, give me epsilon and i will give you delta

[leoraine12]

cAN you teach me how to use the matrix....like this 1

2x+3y +2z = 7

x+y-z=3

5x+5y+2z=3

how to input that one and get the value of x y z???

Can i solve derivatives using elw506??

[xxxxx190]

@bgtanod yes! you can

1. press SHIFT and button labled like integration with d/dx in background

2. type function (for ex. x*x+5)

3. pres RIGHT button (on top navigation)

4. type number for derivation you want to count

press =

that's all

@xxxxx190 thanks!

but can i use elw506 for

differentiation??

[dirindundan]

hi! can i save in the memory a function for exemple f(x)= x-cosx^2 so if i have to calculate f(x1) i just enter the value of x1? ?

@dirindundan unfortunatelly, not
