In this video I demonstrate how to instantly create vertical and horizontal pivot tables using Open Office 4 Calculator. With pivot tables, you can sum up how much a specific person (in a list) has spent and also get this value as a percentage of the total spent.
The added feature is, you can select / deselect specific names in a list, giving you the power to filter information that is useful to you.
Pivot tables will save you a lot of time and energy and knowing how to set them up is an important skill to have whether you're working in finance or marketing. In this fast paced world, shortcuts will make a massive difference to your finances and mental health.

3 Trigonometric Identities You Must Be Able To Derive From Scratch
Derive the trigonometric identities below from absolute scratch...
{cos(θ)}^2 + {sin(θ)}^2 = 1
1 + {tan(θ)}^2 = {sec(θ)}^2
{cot(θ)}^2 + 1 = {cosec(θ)}^2

In this video I explain in great detail and STEP by STEP why the formula for the sum of an arithmetic series is S_n=(n/2)*[2a+(n-1)d]. My goal here on Youtube is to help you understand why certain mathematical formulas exist before you begin working with them. This, I believe, will give you a deeper understanding of mathematical principles.
If this video is a bit too complicated for you, then I would suggest watching the video below first - then returning here at a later date:

In this video I demonstrate how to get cos(π/3, π/4, π/6) and sin(π/3, π/4, π/6) without a calculator. The task can be done simply by using an equilateral triangle and a square. Watch the video to find out how.
