<PRE><B>Question 992186</B>
.
You systematically write &amp;nbsp;senx, &amp;nbsp;which is, &amp;nbsp;probably, &amp;nbsp;sen(x).


In the standard school Math, &amp;nbsp;there is no such function, &amp;nbsp;senx / sen(x).


There is &amp;nbsp;sin(x), &amp;nbsp;which stands for sines.


Do not use &amp;nbsp;senx / sen(x) &amp;nbsp;in future.

Please do not write me more. Thank you.
