#How to make a superscript circle on a laptop code#
In order to create the ® symbol in superscript on a Windows computer, you must turn on number-lock, hold down the ALT button and type the code 0174 on the number pad to the right of the standard keyboard keys. Click the Format menu, select Font and then check the 'Superscript' box. There are a few different ways that you can enable superscript: Click the x² button in the Font section of the Home tab. On a Windows computer, pressing Alt and typing the numbers 0185 while holding the Alt key will insert a superscript 1 symbol. Your highlighted text will be converted to superscript, or you can begin typing at the cursors location to type in superscript. Select the circle/oval under Basic Shapes. The ® symbol may be used simply by copying and pasting it from your computers web browser. Return to the regular font size by repeating the key combination. There are two standards methods of mathematically defining a circle centered at the origin. In the Ribbon, click on the first tab (Home) All the way to the right, click on the icon with a blue circle/triangle/square. The reflection is accomplished by reversing x, y co-ordinates. The reflection is accomplished in the following way: These seven points are calculated by using the property of reflection. If we want to display circle on screen then the putpixel function is used for eight points as shown below:Įxample: Let we determine a point (2, 7) of the circle then other points will be (2, -7), (-2, -7), (-2, 7), (7, 2), (-7, 2), (-7, -2), (7, -2) From which the whole circle can be determined easily.
If a point is P 1(x, y), then the other seven points will be If the calculation of the point of one octant is done, then the other seven points can be calculated easily by using the concept of eight-way symmetry.įor drawing, circle considers it at the origin. The shape of circle is the same in all quadrants.
