I am trying to calculate an algebraic equation using pi and would like to know if there is a shortcut key or if I have to enter the figure for pi.

Enter your number then press (shift) then (X10x) key. That will enter pi. then press (=) for the answer.

Press [SHIF][X10^x]. If it is displayed as the Greek letter Pi, you can still use it as is in calculations.

Please read the manual, it will prove worthwhile.

Your scientific calculator is unable to solve complex equation with complex coefficients. You should try to solve by hand directly using the quadratic formula or by factoring the polynomial in z

failing that, another way would be to set z=x+iy, substitute this for z, carry out the algebra and try to separate real and imaginary parts. But your two equations will constitute a system of two quadratic equations. I am not aware of any general method to solve coupled nonlinear equations.

Good luck.

This calculator cannot manipulate algebraic expressions. You can enter an expression and generate a table of values. You can enter an equation in one unknown and solve it. But you cannot do algebra.

You would need a calculator that has a Computer Algebra System (Algebra FX 2.0, or ClassPad 300/330). Sorry.

You do not need a calculator for this proportion.

For a proportion a/b=c/d, the product of the extrems (a*d) is equal to the product of the means (b*c).

In your case x*x=8*8 or x^2=64.

The two solutions are x=+square root (64) or x=-square root(64).

For a less trivial equation, you can use the**solve** feature of the FX-119ES. To do so, use the ALPHA keyboard to enter your equation; once the equation is typed in, do not press the main equal sign, but the Solve key (the key is located near the top left corner of the keyboard). You will be prompted to solve for X?.

Press key Mode, first select option 5:EQN (by pressing key 5), then option 2: a_nX+b_nY+c_nZ=d_n (by pressin 2).

Now input coefficients from equations in table (each column is for one variable), just type in number and press =, then use arrows to move to another cell.

No, your calculator cannot factor polynomials. You need a calculator that has a CAS (computer Algebra System)

Yes Casio sells calculators with CAS: The FX-Algebra 2.0 and 1.0, the FX-9860GPLUS/GII SD, the GRAPH85 or 80 and the Graph 100+. You also have the CLASSPAD Series 300PLUS and 330.

TI and HP also have CAS calculators.

Texas Instruments

TI 89 /Titanium, Voyage 200PLT, TI92PLUS (discontinued), TI Inspire CAS.

Hewlet-Packard

HP 48G/G+/GX, HP40G, HP49G/G+ and the top of the line HP50G

You can use symbols (X,Y,A,B,C,D, and M, =) to create expressions to use
in the SOLV program or to generate a table of values.

To type them you use [ALPHA] followed by the symbol you want. The symbols on the body of the calculator are of the same color as the ALPHA key. The [=] in expressions is different from the general = sign at the bottom of the keypad.

There are also some typical equations already in the calculator: simultaneous linear equation in 2 or 3 unknowns, and polynomial equations of 2nd and 3rd degree. They are accessed under the EQUATion Mode.

cryshug24 the mode(s) you want to use is mth IO and line IO for algebra. push the shift mode then #1. to write out a long equation push shift mode #2. you have to keep playing between the two modes to get the correct answer.
