Im writing maths paper 2 tomorrow and i know im gonna ace it,your videos really help me a friend of mine recommended them and they really helpfuk thank youuu🎀💗
I don't really know how to explain why (a) is negative 😅 besides the fact that it's not a normal sin graph because usually the point at 90° would be above the x-axis and at point 270° would be below the x-axis,but on this graph it's switched so (a) is negative...idk does that make sense?

for the amplitude you could also say : Maximum Value minus Minumum value divided by 2
I think not, if the amplitude is 2, than the max value is 2, and min value is -2. Therefore, 2-2/2=0
@@malachai_musicNah bruh your maths is a bit off. Max is 2 and Min is -2
So it's 2--2= 4. Divide that by 2 and you get4/2=2 the amplitude
I just look at the dots to see how far they are apart.. it's easier
Thank you so so much for the help Sir! I just finished watching All the videos based on trigonometric functions 😭they helped me a lot!❤️God bless
Me and the other grade 11s are so overlydepend on your videos I think its unhealthy 😂
Unfortunately and fortunately it is true😔
Now this is the true math experience
Thats so true😅❤
Am in grade 12 watching this😂 and actually participating😅
I so wish to be you this is tough in grd 10 😭💔
common guys he deserves more likes
Hi Kevin, This video is so helpful! Thank you!! For question 4.5 is the answer not 90 and 270 degrees? (0 - - 2 = 0+2 = 2)
No, the question said f(x) - g(x) so the answer would be -2-0=-2
@@panooooo.momg thanks so much, I also thought it could be 90 and you literally saved my life 😭😭😭😭❤❤
Yess@@panooooo.m
@@panooooo.m I think -0 -(-2) still =2 no?
Hi this is so helpful thanks
I'm writing in less than 6 hours
Where are u located
In question 4.2 how do we know if we are focusing in either cos or sin
Thanks a lot
2:00 why is (a) negative and (b) positive ?
(b) is positive since it's a normal cos graph and the amplitude if the graph were to continue into the negative range would be 1

@@Niefa-ti9td nah
@@MOXX101 wdym you don't understand or I'm wrong 😅
@@Niefa-ti9td nope🥲but thank you for trying to explain
haha my teacher played this on her laptop to my classroom at school today :)
that's crazy
More videos Sr 😊
Kevin pls do photoelectric effect g12😔😊
Life saver
I’m writing in 15 minutes
The memo for this in 4.2 includes the 0 and 180 so I don't know which is which😢.
Watching this vid at English class
Why a =-2 because a is always positive
😭😭
Im littery writing
I feel like I am ready to leave my family and just marry you
Thanks daddy
