![]() ![]() Whereas the Alpha button allows accessing all the red options instead. By pressing the Shift button we can access all the functions in yellow color of the calculator. ![]() On this section we would like to highlight the functionality behind the Shift (yellowish label on the top left button of the keypad) and Alpha (red label button right beside the Shift). You can download the manual for this calculator on this link. The more complex ones are included in the calculator manual. The Casio fx-115ES Plus has a lot of features to share. Once data s entered, coefficient results are displayed independently. Notice the option to select between linear, exponential and many other frequently used forms. For this all you have to do is to refer to the chart imprinted on the calculator’s hard shell case.Īdditionally you can perform basic statistics calculations or regressions. For all this to take into effect it is required that you select your standard form and identify the appropriate coefficients.įor the benefit of science and engineering students the calculator features 40 built in scientific constants and 40 common unit conversion units and translate between typical units of weight, volume, distance or temperature. Another important inclusion of the Casio fx-115ES Plus is that it can compute the roots of several standard polynomials or solutions to polynomial inequalities. Yo can enter your equations using one of the nine built-in variables and follow the prompts to identify known values. Although we have to keep in mind these are just approximations. The built-in solve feature can approximate the solution of many simple equations. Another advanced and extremely easy to use feature is the included templates for logarithm of any base or for summation and all these support the natural display that can take the input or output of expressions like you have never seen before in a scientific calculator. ![]() Using computational techniques it can approximate the definite integral, or the slope os a function at a given point. If you thought this calculator couldn’t do integrals, you will be surprise to know it actually can. The Casio fx-115ES Plus also performs great in calculus. You can enter a trigonometric expression exactly and get an exact answer. One of the more distinctive and outstanding features is that you can enter expression just like you see them in text books. This calculator will provide all the functionality that you’ll ever need.ĭecimal approximations are to be expected on a scientific calculator, but this one supports fraction, roots and even repeating decimals. The functions on the Casio fx-115ES Plus are geared towards operations on advanced mathematics, engineering or calculus courses that do not allow to have a graphing calculator. This is a fairly cheap calculator yet powerful enough to match the level of many graphers on the market. The Casio fx-115ES Plus is the most advanced scientific calculator suited for all ages and levels of education.
