Extremely well explained.Thank you so much!

Thank you so much. I was confused by the notation. Now I get it!

Needed this for a ray cast demo program that I am trying to make thanks, it really helped

Very well explained, thank you!

Love how you are a visual explainer. May I ask what software you use for writing and screencasting?

Thanks for the helpful information!!!

I do not understand why the rule V1+V2 = (X1+X2), (Y1+Y2) Does not work? That would get (-1+4), (6+3) since P us the starting position? Why are you starting with Q and why are u using - instead of +?

Thank you

Thank you!

So the distance between two points is just sqrt((Bx - Ax)^2 + (By -Ay)^2) ?? Correct me if im wrong but thats what i understood

Could you also say vector is -5,3 ?

Thanks

👌👌👌👌👌

Don’t you need to calculate the square root? Or do you just leave it there and that’s your answer?

I would say 3 significant figures. But it ultimately depends on whether the examiner is asking for a certain number of decimal places

Thank you!

Thank you
