Mashine ya Kuhesabu
Plot anafanya kazi kwenye dromu inayohusisha matumizi ya mtandao bila kutumia marki ya kuainisha, bila kutumia ishara.
y = f(x), e.g. x^2-3, sin(x), 2*x+1
Kuhusu kifaa hiki cha kupigia hesabu
A graphing calculator draws the graph of one or more functions of x. Enter equations like y = x^2 - 3 or sin(x), and the calculator plots them on an interactive grid you can zoom and pan. Add several functions at once to compare them, each in its own colour.
It evaluates each function at many x-values across the visible window and joins the points into a smooth curve, redrawing as you scroll to zoom or drag to pan so the axes and grid always rescale to what you are looking at. Any expression the scientific calculator understands works here — polynomials, trigonometry, logarithms, exponentials, roots and combinations — and each function you add is drawn in a distinct colour so several curves can be compared on one grid.
For a worked example, plotting y = x^2 - 3 gives an upward parabola whose lowest point sits at (0, -3) and which crosses the x-axis near x = -1.73 and x = 1.73 (where x^2 = 3). Add y = x - 1 on the same grid and the two curves meet where a line crosses the parabola, giving a visual solution to x^2 - 3 = x - 1. It is used to explore the shape of a function, find roots and intercepts, spot maxima and minima, and see where two graphs intersect.
Maswali yaliyoulizwa mara nyingi
Nitaingiaje katika kazi hii?
Piga chapa ya x, kama vile x mwone2, exx-1 au 2*x+1, kwenye mashine ya kupigia hesabu. Unaweza kuongeza kazi mbalimbali na kila moja imechorwa kwa rangi tofauti.
Je, ninaweza kuishi na kula na kula tambuu?
Hati - kunjo au tumia vidude vya thim hadi kwenye bustani ya wanyama, na uivute grafu hiyo kwenye pan pantra.
Ninaweza kupanga mambo gani?
Maneno yoyote ambayo sayansi hutoa yanatia ndani falynotias, trig, magogo, vitu vya asili, mizizi na mchanganyiko wa vitu hivyo.
Ninapangaje mambo mawili ili kujua mahali ambapo yanaingiliana?
Kwa mfano, anza kufanya kazi zote mbili kwenye mstari wake, y = x2 - 3 na y = x - 1.
Ninagandikaje parobola kama y = xÉ2 - 3?
Type x^2 - 3 as the function. The result is a U-shaped parabola with its vertex at (0, -3); zoom out or pan to see where it crosses the x-axis near ±1.73.
Je, ninaweza kupanga mambo yanayoweza kufanya mtu akiwa na akili na akili?
Yes. Enter sin(x), cos(x) or tan(x) and the wave is drawn across the window. Combine them with other terms, such as sin(x) + x/2, to see the combined shape.
Kwa nini gloma yangu huonekana kuwa tupu au bapa?
Huenda kona hiyo ikabaki nje ya mandhari ya sasa. Zoom nje au pan mpaka iingie katika safu ya milima faida kubwa au ya juu ambayo mara nyingi unahitaji kutoka kwenye bustani ya wanyama ili kuona umbo lote.
Matokeo ni makadirio ya mwongozo wa ujumla, si wa kifedha, wa kitiba au wa kodi tu.
