Why can't plot circle? (x+3)^2+(y+5)^2=9 is equal to y=±sqrt(9-(x-3)^2)-5, just enter 2 equation(±, so one +, and one -) and plot it, you will find the circle

Darko Aqua

Great and simple Would like 0.1 for coarse and 0.01 for fine x axis steps instead of irregular intervals. Other then this excellent app. Thanks!

Anand Daswani

Has an excellent interface n does everything that one wants to do with graphs!! Love it Has an easy interface, allows more than 1 graph simultaneously, has diff colours, works well n looks good 😎

Yolo MCSwagger

Very good ! I recommend 100% Very good and sooo practical!Now i can verify very easily if i made my graphs right !

Chris Knowles

Can't graph circles, other non functions You can only address x as a variable, so any equation with x and y as a binomial is off the table. Also, the visual design leaves something to be desired.

Omar Mohamed

Pretty good ! Very easy to use ,Very clear ,Fast ,No lag at all , I use this app to check the answer of the math questions . Nice work and thanks

User reviews

Really good app If you need to do graphics, just put it in. It will precisely show you what you need. It has a very clean and beautiful design and it's very easy to use. The only thing that saddens me it's the fact it can't do even more. Some graphics it just can't do. But yes, definitely recommend!

OK, but major flaws Firstly, there is the fact all equations must be equal to f(x) , excluding the possibility of drawing circles. Secondly, the intersection finder just finds the intersection on the screen, then works out the coordinates from that, making it close, but wrong. For example the solution to f(x)=x, f(x)=0 was 0.003877, 0.001912, not (0,0).

Редактирование вызывается долгим нажатием по пункту, который хотите отредактировать.

Начиная с версии 1.14:

- Чтобы добавить пункт высчитываемый в процентах от общей суммы (например какой-нибудь налог) нужно в графе "Единица измерения" поставить знак "%" (без кавычек), а в "Стоимость" число сколько процентов.

- Чтобы сделать скидку в процентах делаем то же самое, только в "Единица измерения" ставим "-%", проценты будут вычитаться.

## Geometry Pad

Geometry Pad is a dynamic geometry application for Android tablets with universal appeal. Teachers can use it in a geometry class for better students engagement and deeper understanding of geometric concepts. Students would benefit from using Geometry Pad while working on geometry assignments at home as well. Easily create complex geometric sketches, measure everything you have in your document, experiment with shapes and transformations.

Use following tools to sketch your geometry constructions (*):

- Move and scale. Scroll the workbook by your finger. Pinch and zoom the content of your workbook. Move and modify geometric shapes.

- Compass to create arcs.

- Point. Plot a point on the workbook. Customize point name and color.

- Line. Create a line. Customize line style, color and start/end points. Calculate line length (distance between points).

- Midpoint for lines. Show/hide midpoint for lines and polygon sides. Snap to midpoints.

- Parallel, perpendicular and tangent lines. The lines can be created as easily as regular lines. Just create and move the line until it automatically snaps to parallel, perpendicular or tangent.

- Angle. Create an angle with up to 1 degree precision. Customize angle line style and color.

- Triangle. Create a triangle of one of the predefined types: regular, right triangle, isosceles, equilateral. Customize sides style and color. Calculate triangle perimeter and area. Calculate inner angles of the triangle and length of its sides.

- Triangle lines. Create altitude, bisector and median lines in a triangle. Calculate length of triangle lines. Customize lines style and color.

- Quadrilateral. Create a quadrilateral of one of the predefined types: regular, square, rectangle, parallelogram, rhombus. Customize sides style and color. Calculate quadrilateral perimeter and area. Calculate inner angles of the quadrilateral and length of its sides.

- Circle. Create a circle. Calculate circle perimeter and area. Easily create circles inscribed into a triangle by placing circle's center close enough to the incenter of a triangle.

- Circle radius and chord. Create radius and chord lines for a circle. Customize lines style and color. Calculate the length of the lines.

- Polygons and regular polygons.

- Arcs and circular sectors.

- Ellipses.

- Text annotations. Create floating and pinned single and multiple lines text annotations. Customize text/background color and transparency.

- Measurements tool. Measure shape properties in single touch. Measure intersection points (line & line, line & circle). Use multitouch to measure distance between points and angle between lines.

- Transformation tools: rotation, reflection, enlargement and translation.

- Manual input of coordinates, lengths and angles. Use manual input to precisely locate points, setup custom length for a line or a polygon side, and change angle value.

- Built-in calculator: basic arithmetic functions, square root, sin, cos, tan.

Manage multiple documents with your geometric sketches at the same time using Save and Load features. In addition, you can share documents through e-mail or Dropbox.

Some of the tasks you can solve with Geometry Pad:

- Create geometric shapes and measure all its possible metrics like length, angle, area, perimeter, intersections, distance between points, angles between lines.

- Move/resize geometric shapes and watch how its metrics are changing in real time.

- Demonstrate circle theorems by creating and changing inscribed and center angles.

- Demonstrate theorems about incircles and excircles locations.

- Create and annotate complex geometric figures. Share them through export to image and e-mail features.

* Geometry Pad is a commercial product and some of its features are unavailable in the free version. A paid in-app unlock is required to get access to the premium features (Premium Features Pack).
