Afternoon guys. I've had a lot of people contacting me asking if I can just go through a few basics regarding some of the more interesting maths principals. I'm a bit busy, but I'll see what I can do. Take your common or garden isosceles triangle - you'll find that there are only 2 equal sides as opposed to the 3 you'll find in an equilateral triangle. Thing is, guys, we're not dealing with equilateral triangles here. No way. These are isosceles and they deserve a bit of respect for what they are. Don't get me wrong, the internal angles still equal 180 degrees .... oh god yes. That's a given with any triangle whether it be isoscles, scalene or whichever you want to mention. I know it's not easy to take in so I'll leave you to digest what I've said so far. When I think you're ready, I'll be introducing the logarithms theory of John Napier and a few basic properties of cosine tangents. Until next time, guys. Take care. God bless.
