[FIXED] how to show square root symbol in php code using gd library?

Issue

I am now dealing with a mathematical problem with my codes. I have second degree equation , for example , ax^2+bx+c=z .

If we have to find the value of 'X', we have the eqution , x=(-b +/- root(b^2-4ac))/2a.

The main headache is that i've to show the square root symbol in image using gd library. But i dont know how to show this equation using proper mathematical(i mean using square root symbol etc.) in the image using gd functions.

Is there a way for doing it?

Solution

Should work in imagettftext - √. To do it Mac you hold Alt (option) + J

You can use an image (BLOB) from a mysql database as wellas well as string data and it will auto detect it and creates a GD resource based on it. The image has to be supported but i'm sure the square root symbol is. Good luck I hope this helped.
