This is giving me all sorts of nightmares so I am happy that someone competent is going to explain this bit of maths to me.

Hi

I wish I was your student though I am pretty good at maths and I too have great teachers where I live but you are just above them when it comes to your way of explaining things

Could you do a video on equation of a circle contained between two curve , one curve and a straight line & between 2 straight line.please

Long story short, I never saw any of this at school for reasons.
So this is the first time hearing/reading these things, because I've encountered it in my programming courses I wanted to know more about it.
All in all I find the explanation given incredibly clear and helpful. I'm sure would I have learned this at school it would have taken a great deal longer before I understood than from this video.
There's just one thing that bothers me... Since about 3:50 I have been wondering about the 3rd figure at the bottom left but you skipped it after your explanation about what the words mean.
Is that line on the third figure not both a Tangent AND a Secant?
