What are the equations and its kinds? - Computers & Internet

when programming, please use a decent spacing, else nobody will see an error when an obvious one exists. "pep8".
if i is a variable... ok, no problem we overwrite that ?1????, then please do not redefine it in a loop as a number. (This would have been a second alarm while reusing i...) Nobody does this, so this atypical error cannot be seen at a first glance. In our case this brings the error as follows. After the last i-loop this "global variable" has the value 2, and we try to solve a system of equations, where one of the equation variables is the constant 2. The error message is also misleading.
give a minimal code showing the error, only needed lines of code.
use list comprehension.
do not call a list eqns, when it does not collect equations, but rather entries of a matrix. The solve of these "equations" will be hardly detected with bare eyes as an error.
try to give pointed prints. The show command delivers a mess, is not a good control of the operations.
the two definitions of eqns and xlist are not needed. The wording for xlist is also not proper. Something like X_entries would reflect the provenience, but we do not need this new variable, the matrix X already has the information.
Please understand that these "critics" are just kind advices, at any rate not offensive, in my case, knowing these as i started programming in python would have been a real benefit.

Is it complex or matrix? You can have only one mode at a time.What kind of equations? The solve function uses real-valued equations.
Complex numbers: You can add, subtract, multiply and divide. You can convert a number from rectangular to polar forms and vice-versa; you can calculate the absolute value of a complex number, or a conjugate.
All the operations are done in the Mode CMPLX.

Hi mavekae,

If you are just trying to solve a simple quadratic equation by entering coefficients, this calculator does have those features. The TI-83 is a better choice for that kind of function.

1. Number of 0.25 coins is x, number of 0.10 coins is y and number of 0.05 coins is z.
2. First equation is 0.25x+0.10y+0.05z=36.
3. You also know that z=4x and y=x+30.
4. You substitute that in first equation and you get: 0.25x+0.10*(x+30)+0.05*4x=36 or 0.25x+0.10x+0.2x=36-3 or 0.55x=33
5. Now you know that x is 33/0.55=60 and y=x+30=90 and z=4x=240.

Ah, word problems! The trick is to convert the given information into two equations in two unknowns. Let's let S be the number of solid color rolls sold, and P be the number of print rolls.

The first equation is easy:

(eq. 1): S + P = 480

We're given that information: the total number of rolls sold. For the second equation, use the given price information ($4/roll for the plain, $6/roll for the print).

(eq. 2): 4S + 6P = 2340

Again, we're given the total sales, and we know how much each kind costs.

Now it's just some basic algebra. Let's rearrange equation 1 to get S by itself:

S = 480 - P

Then use that value in equation 2, and solve for P:

4S + 6P =2340
4(480 - P) + 6P = 2340
1920 - 4P + 6P = 2340
2P = 420
P = 210

Now we know that the MLHS band sold 210 rolls of print paper, which means they sold 270 rolls of solid. You can your answers in the original equations. If they are the right values, both equations will work out.

270 + 210 = 480, eq. 1 is right.
(4 x 270) + (6 X 210) = 1080 + 1260 = 2340, eq. 2 checks.

The drain pump might have gone bad, check if the drain pump is making some kind of noise and also check if the drain pump is not obstructed.
You can open the coin trap on he right hand side bottom of the unit and clean the same for any blockage.

well it depends on what kind of handle it is.but you can get a lot of what you need at Home Depot,Lowes,or sometimes Walmart.But like i said it all depends on what kind of handle......
