Thanks to the awesomeness of the interwebs, that we have managed to get hold of this amazing piece of sheer genius in motion. First of all, have a look at the image itself.

I call it – Trigonometry in Motion. [ Courtesy: Reddit ]
The idea here is that in the circle, if you look at the special angles i.e. 0, 30, 45, 60, 90 degrees etc. for the first positive quadrant, all these angles are some combination of 1/2 , sqrt (3)/2 and sqrt(2)/2. And these keep oscillating amongst the special angles.
Or the easy way to remember this back in the days was SOH-CAH-TOA. As in, Sin = Opposite / Hypotenuse, Cos = Angle / Hypotenuse, Tan = Opposite / Anlge.
And now let’s go for a geek nitro booster after the jump.

So, I thought I would share them with my beloved readers. This section: Excel Tips aims at sharing the small tips and tricks that I have come across which makes life easier for anyone working with Excel or VBA Macros. Cheers!
Here we’ll be focussing on how to select a range dynamically and perform further operations to it etc.
For e.g. If we have a Sheet “Input” of which one cell is required say column B, and we need to perform some kind of mathematical operation on them – viz. average, sum, etc. we need to do that by selecting the entire range of non-empty values of those two cells.
The problem here is that the number of entries in column A will vary from time to time, but we want a command button which automatically knows the amount of non-empty values and accordingly runs the mathematical operation. This is known as Dynamic Range Selection.

This post should not be considered as just a mere rant. This actually works for job interviews and in my experience of the few that I have attended, it has certainly got the positive attention of the recruiter. So, how does it work? By definition, blogging can be at different levels – personal – which is focussed on personal likes/dislikes etc and hence, is already driven by some niche.
