I feel that today was a fairly easy day as i have learnt topic related to this topic in this term. This topic would be a really applicable function in real life. However i feel that more questions will be needed for me to fully grasp the idea of the topic. Also, the internet resources provided a great platform for me to search for other information related to finding distance and the mid-point. In a conclusion, today's learning was fruitful and i look forward to learn more on this topic to combine it with the two previous topics.
