Please don't ever take these down. You are SO HELPFUL!!!! Thank you so much!
Label angles correctly...they go anticlockwise..plis u confuse me
??
In the last example the value she obtains corresponds to the one with the calculator in Radians. The correct answer is 8.03 to 3s.f.
Thanks
last question i get 8.0348 not 9.313
Can i also add.. You are by far the best maths tutor on the internet. You have helped me immensely. Thank you so much for taking the time to create and upload these videos. You're enriching peoples lives
Same 😅 I think that she wrote the wrong thing into her calc
I also got 8.03m^2 ....I think that was her mistake
@@mishcafreebury-wt6vh don't worry you're on the right path ,you're going to do great. Keep up the good work
Watching this video 2021 and it so helpful . thank you so much for not deleting this video 💕
this video is very helpful, i love the positivity please keep uploading about different topics in maths, thanks alot
Thankyou!! So much for not deleting this video it help me alot 😊you the best❤
Thank you so much I was so so confused about diff formula for triangle but now I understand where to use formula.
you are so underrated
I like u po how you teach madali Lang Ako Maka intindi thank you po
Best video I have come across
Thanks it helps a lot.❤
Im left with 3 months to write my o level exams and this pretty helpful
i love how u speeeeak
Hii!!
I was wondering if you could post videos on 3D trigonometry .
It would be really helpful.
Thank youu!!
Thanks!
THANK YOU SO MUCH
Last question I get 8.03 not 9....
yes
Me l go 9 point something like her answer l'm using advanced D.A.L calculator
Thanks 🙏
You’re welcome 👍
I like your presentation. If you use the formula : sine squared + cosine squared = 1 , we can substitute the equality of the square root of the sine squared of the particular equation mentioned and substitute it into your formula, 1/2 ab sine C. We then use the Law of Cosines and substitute its formula into the formula we discovered. By further calculations we discover a new formula for the area of a triangular. The new formula is unique in its properness. Although you no longer need to know any angles by an entangled knowledge of the values of the sides we produce an area of a triangle. (See 1 John 5:5)
Thanks miss
Thank you so much!
You're welcome! 😄
God bless u
last question is 8.03 lol
For the second question i got 10.1?
80 divided by sin60 is a negative value, and you cannot square root a negative to find x, this triangle does not exist.
Aussie?
Ah
Dkl props
She is so beautiful 😍 get rid of Carol vorderman and get this little beauty on the TV babestation is always wanting new girls
I fell in love 😘 with u.
