Hi maam can I ask if we can use the turning point formula to find the turning point?
Thank you your videos are very helpful 😊
Excellent explanation. Could you please make a video on finding the equation of a tangent for a standard parabola? Thank you
You still posting!!!! 😭😭😭

Amazing
You have a beautiful voice. I have an associates degree in Mechanical Engineering and Civil Engineering and you did this so beautifully. I am watching videos because I am thinking about getting my bachelors degree in Civil Engineering or possibly Mathematics. Again that was beautifully done and easy to follow
Very clear explanations, thank you
You are just the best 👏👏
Great explanation . Thanks ma'am ❤
How about along the line of symmetry?
Thank u miss😊
Where did we get zero from 😭
This is excellent ❤
Thank you, very well summarised
Gave so much clarity thank you❤😊
Finally , I understood what Reduction Formula is . Thank you Grace Maths 🙏
You are welcome!
Thanks. IT WAS VERY HELPFUL 💘💘💘💘💝💝💝💝
I'm so glad!
thanks so much😁 @@gracemaths9588

THANK YOU THANK YOU SOOO MUCH❤
You are so welcome!
🙌
Thank you so much!!
Thank you❤
Thank you!
Very helpful
-5×-1=5 it does not give you -6 which we are looking for but -3×2=-6 which gives us the answer we are looking for
Thank you sooooooooooo much
Thank you
Great 👍🏿
Very helpful
Thank you 👍
Thanks. Very helpful.
Learnt more in 7 minutes then in an hour class. Thanks 😊🙏
U rock mam!!🤩👍
Pleasure
There is a mistake, in example 7.we were calculating the gradient of AC. And you didn't use those coordinates
Thank you so much for pointing that out and well done for picking it up!
Thanks for clearing that up👍
Than you so much this helps me a lot
This was so helpful.
Thanks for the help i have been struggling with this for two terms
In the final problem, when calculating the gradient of AC it seems the incorrect coordinates have been used. instead of using the coordinates of A and C the coordinates of B and C were used. If my observation is correct then the final answer is incorrect. Can someone please double check this incase my observation is wrong.
Hi Donthe, you are correct in that there is an error, but it is simply the naming of the gradient of BC is incorrect. I named it the gradient of AC instead of the gradient of BC. The answer is still correct. Thank you for picking up the errror.
Hello maam
