In a recent post on the Cauchy-Schwarz Inequality I wished to "size" the parentheses adequately in the expression \(\displaystyle x = \frac{ \langle x, y \rangle }{ \mid \mid y \mid \mid^2} y + ( x - \frac{ \langle x, y \rangle }{ \mid \mid y \mid \mid^2} y ) \)... ... but in order to use \left and \right I need to also use the Latex Code for ( and ) ... but what is the code for a left and right parenthesis ... ?Hope someone can help ...
