Hi,
I am very much new to VBA programming, started just two days ago.
i need to write a code which uses cos and sin functions.
i tried using Sin and Cos functions.

but i have got a strange problem, that when ever i type Cos in VBA editor , as soon as i hit enter Cos is changing to COS.

I actually tried to create a function named COS and call Cos from that Initially,
But i deleted, since then whenever i type Cos it is changing to COS.

Please help how to solve this problem.

Thanks in Advance.
