reduce the speed from settings on the video.
The concept is explained very well, thank you for that. But 2 recommendations: 1. In the question, d >= +/-16 but you have proved the answer to be d from (-infinity, -16] and [16, infinity). When d > -16 how could it take the values from (-infinity, -16]. Shouldn't the answer be from [-16, infinity)? 2. The use of highlighter could be reduced, sometimes it is only causing the distraction instead of helping in focusing on the concept you are explaining.

Hello Anurag. Glad to know that you found the lessons helpful. Point 1: The solution for the question will remain the same as given in the lesson. Nevertheless, you do have a point here wrt to the inequality : d >= -+16. The inequality: d^2 >= 256, should instead be followed by: d >= |16|. Thanks for pointing this out. I'll have the team change that step soon. Point 2: Noted. Thanks for the constructive feedbacks.
Thank you for the course sir. The concepts are really explained well!
