解方程計算機

Puli_College 為工程師及工程科系學生發展一套計算機，分別為基礎計算機、科學計算機、統計計算機，以及解方程計算機。
本機為解方程式型計算機，專為方程式f(x)=0之解答設計。其中f(x)可包含常用函數如三角函數，反三角函數鍵，雙曲函數，指數及對數函數等等，適合科學及工程解答用。
解題時首先輸入f(x)，例如f(x)=(x-1)(x-2)(x+1)，按下解答鍵solve即可獲得f(x)=0之解答x = 1，x = 2，及x = -1。欲進行下一題目時，先行按下清除鍵，clear，即可。雖然很罕見，但由於計算資源為有限，並非任何解答都可以藉由本機獲得；例如方程式f(x)=(x-a)^(0.5)=0，當|a|<0.5時，經由本機即無法求得解答。
與Puli_College其它型計算機相同，個別按鍵並非任何情況下皆有效，於是，任何按鍵均區分為有效及無效兩種情況，有效按鍵顯示為較明亮之按鍵原色，無效按鍵顯示為較暗淡之半透明背景色。 Puli_College for engineers and engineering students to develop a computer department, were based computer, computer science, statistics, computer, computer and solving equations.
    This machine is a solution of equation computers, designed for the equation f (x) = 0 solution of design. Where f (x) may contain commonly used functions such as trigonometric functions, inverse trigonometric functions keys, hyperbolic functions, exponential and logarithmic functions, etc., used for scientific and engineering answers.
    First enter f (x) when solving problems, such as f (x) = (x-1) (x-2) (x + 1), press the answer key to solve to get f (x) = 0 the answer x = 1 , x = 2, and x = -1. For when the next title, first press the Clear key, clear, can be. Although very rare, but because of the computing resources are limited, not any answers can be native obtained; for example, the equation f (x) = (xa) ^ (0.5) = 0, when | a | <0.5 when, via the machine that is Unable to obtain the answer.
    Puli_College other with the same type computers, individual keys are not valid in any case, so no keys are divided into valid and invalid both cases, the effective key appears as the brighter colors of the button, the button appears as invalid the semi-transparent background is dull color.
