A powerful, flexible graphing calculator . . . and it's free!
Does far more than most of the paid calculators out there . . . let alone the free ones.
Features:
1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
2) Graphing. Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Graph in polar coordinates.
• Graph parametric equations
• Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this!
3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework!
5) It can make a table of the values of a function you enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition.
7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.
8) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line. Also statistical distributions (under functions > statistics) -- beta, Cauchy, chi, chi squared, continuous uniform, Erlang, exponential, Fisher-Snedecor, gamma, inverse gamma, Laplace, log-normal, normal, Pareto, Rayleigh, Student's T, and Weibull.
I'd love to hear your comments or suggestions. Because of spammers, my email address is not in this description, but it is inside the app, and it's great to hear from real users.
一个强大,灵活的图形计算器。 。 。并且它是免费的!
确实远远超过大多数计算器支付更多的在那里。 。 。更别说免费的。
产品特点:
1)科学计算器。简单掌握,易于使用,但强大的功能可当你需要他们。可用功能包括以下内容:
•常用的算术函数和指数。
•平方根,立方根,n次方根,自然对数,将基准站10,日志任意基地,绝对值,阶乘,排列(NPR),组合(NCR),模数,随机整数,钟形曲线,累积正态分布,小数到分数。
2)图形。功能:
•图形多达四个方程一次。
•图形标记。
•您可以拖动图形或捏来放大或缩小。
•计算器可以找到根源和十字路口。
•在极坐标图。
•图形参数方程
•可以绘制隐函数,如x ^ 2 + Y ^ 2-4 = 0。大多数应用程序的计算器不能做到这一点!
3)单位换算。用一个水龙头,你可以输入你转换到计算器的结果。加速度,角度,面积,密度,距离,能量,力,质量,功率,压力,速度,温度,时间,和体积:目前的下列不同的单元进行转换。非常适合做物理功课!
4)常数进行科学计算 - 光速,重力在地球的表面强度,等等,等等攻上不断将其插入到你的计算 - 也就是说,你不必在值键。再次,非常适合做物理功课!
5)它可以让你输入一个函数的值表。您可以选择表的起始x值,以及多少x的增加为每个连续行。
6)帮助屏幕直接链接到许多可用的功能和常量。点击箭头披露看到的定义。
7)忘记了二次公式?或双角公式正弦和余弦?数学/理科参考命中高点各学科。目前包括代数,微积分,几何,三角,向量,矢量微积分和经典力学。
8)统计 - 输入数据并进行直方图,盒须图或散点图可选回归线。另外统计分布(下功能>统计) - 测试版,柯西,卡,卡方,连续均匀,二郎神,指数,费舍尔斯内德克,γ,反伽马,拉普拉斯,对数正态分布,正常,帕累托,瑞利,学生的t和韦伯。
