Casio FX-115ES Scientific

$18.00 Est. at Amazon

from mastermind278, www.pricegrabber.com
it is also great that this calculator has a decently sized screen compared to other scientific calculators, so it is possible to write long equations and be able to see what you have written.
from www.amazon.com
i was very impressed with the capabilities of this inexpensive calculator - it did everything i would want for the exam, except perhaps being able to store pre-programmed equations, like the hp-33s.
from www.amazon.com
the matrix reduction capabilities has been a major time saver especially on tests, particularly for solving systems of linear equations especially in my statics, dynamics, and strength of materials
from www.amazon.com
3) the algebraic/textbook entry becomes cumbersome for doing long repeated calculations -- also, there's no way to store an expression/formula/equation for use after (auto) power-off.
from www.amazon.com
the large, "natural" display is my favorite feature and makes inputting equations much more simple.

Casio ClassPad 300 Scientific

from www.amazon.com
with quite a few more functions than standard graphing calculators on the market, and helpful programs such as the equation solver, the classpad, with its state-of-the-art technology and easy to use
from www.amazon.com
the classpad solves that, by its natural math input (think word's equation editor).
from www.amazon.com
i like its ability to check two sides of an equation to make sure thy are equal as well as the ability to drag and drop equations into different programs to graph them or save them.
from www.amazon.com
it addition, however the casio (os 3.0) will do now do dirac delta functions, heaviside step functions, fourier and laplace transforms (including fast fourier transforms, i.e., fft's), first order

there is no way to enter a generalized equation with multiple variables, such that the user can enter all of the unknowns except one, and have the calculator solve for the remaining variable.

of new functions such as complex numbers (useful in electromagnetics) hex and octal conversions (digital logic) three variable equation solving (algebra and later on differential equations).
from www.amazon.com
the matrix and equation functions are nearly identical on the two calculators.
from www.amazon.com
i used that same calculator all through college, slowly learning the significance of new functions such as complex numbers (useful in electromagnetics) hex and octal conversions (digital logic) three
from www.amazon.com
there are also six modes that can be set to work within such as: normal for integration, ordinary number crunching, etc., complex numbers, matrices, lists, equation solving, etc.

HP HP 33s Scientific

Hewlett Packard HP 33s Scientific Calculator

$50.00 Est. at Amazon

from www.walmart.com
this calculator is exactly what i need for work, and performs complex match equations remarkably well.
from www.amazon.com
it is clearly meant for folks who punch lots of equations rather than someone who wants to program a calculator.
from www.amazon.com
if you want to make or use complicated programs, consider the hp48gx (also rpn).it can perform definite integrations, and given an equation in one variable it can solve for it numerically.
from www.amazon.com
it does an excelleent job of covering the scope of the 33s's functionality, with emphasis on equations and programming.
from www.amazon.com
the calculator is programmable with equations, can perform integrations, and can solve equations via hp's solve application.

Casio FX-9750GPlus Graphic

$59.00 Est. at Amazon

from www.pricegrabber.com
the functions are really useful; two in particular that i've used the most are the equation solver and the matrix calculation, which simplifies calc steps and saves time.
from www.amazon.com
i also like the equa feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations.
from www.amazon.com
doing polynomial equations is simple, expecially when compared to a texas instruments' version.
