Baibhab Bose said:I don't know how to type mathematical symbols and equations and stuff. Like if I want to ask something here in physics forum, I need to type mathematical expressions like everyone here does. How can I do that? Do I need any software?
Thank you so much!'PeroK said:You don't need any software. Try reading this.

Also, if you find an example of an equation, you can "reply" and that will give you a copy of what they typed. You can then cut and paste this into your own post.
To type an exponent, use the caret symbol (^) followed by the exponent number. For example, 2^3 will display as 23.
To type a fraction, use the forward slash (/) to divide the numerator and denominator. For example, 1/2 will display as 1/2.
To type a square root, use the sqrt() function and place the number inside the parentheses. For example, sqrt(4) will display as √4.
To type Greek letters, use the backslash (\) followed by the name of the letter. For example, \alpha will display as α.
To type equations with multiple lines, use the align environment. Use the & symbol to indicate where the equations should align. For example:
\begin{align} 2x + 3y &= 7 \\ 4x - 5y &= 2 \end{align}
will display as:
2x + 3y = 7
4x - 5y = 2
