Hi Nese, I will get a lesson up for you next week on this! If you also have a look at the Trigonometry lesson (go to 11 mins 22 seconds), I talk briefly about the table that you can memorise for the non-calculator exam. The other method is using triangles, I only advise using the triangle method if you are planning on taking A-Level Maths, otherwise it's easier to just memorise the table.
If you also have a look on YouTube, there is a way you can learn them using your fingers. Just search 'exact trig values fingers' and you should be able to find a video that takes you through this 🙂
The lessons go live on a Monday and Wednesday at 4pm, and on a Saturday at 10am, but they are then saved for 21 days for you to catch up on whenever is convenient for you - so you don’t have to watch them as they go live!
You are more than welcome to request any lessons too, and I’m always available for you to ask any questions you have 😀
Hello, if you click on the 'Topic Booklets' tab in the top menu you will get to the page where you can find all of the written problems - let me know if this still doesn't work for you!
Hi Laura, please could you help me with this question? I used the quadratic formula to find the values of x, but I don't know how to show how you get that equation?
You need to find the area of the shape you have been given in terms of x. I have done this by splitting the shape into four parts and finding the area of each. You can then collect all of your like terms and make your equation equal to 100, as you have been told that this is the area!
You will be able to use your current answer in part b! You will take x = 3.5 as x needs to be a positive number (as it is a length)!
Hi Ayesha, yes you can but you would also need to state that you have used AAS (Angle, Angle, Side) to prove that the triangles are congruent!
Make sure you that you have still stated and proved that AB = AD, and also proven that either angle DCE and EAB or angle ABE and EDC are equal, as you cannot use three angles to prove that triangles are congruent - this would just prove that they are similar! 😀
To solve this you needed to make either x or y the subject of the second equation, and then square it (using double brackets), and then substitute it back into the first equation - have a look at the workings below!
hello , i am Nese . i would like to request a lesson on bearings for next lesson
Hello , i wanted to ask if you can do a revision lesson on exact trigonometry values please .
Hello , I am Nese . I was wondering if you can do a video on probability questions with fractions and ratio.
Hello, I was wondering if the revision lessons with a tutor is set at a specific time and date each time. Or can it be according to my schedule?
Hi Laura, I cannot find the written problems, once I click the same it takes me to sample bracket. Please advice.
Hi Laura, please could you help me with this question? I used the quadratic formula to find the values of x, but I don't know how to show how you get that equation?
Hi Laura, I’ve just got a test back in class and still don’t understand what to do on question 9a? Please could you explain
Can I use the reason:
Angle AEB = Angle DEC because vertically opposite angles are equal
Hi Laura, please could you explain how to answer this question? I have no idea where to start!!
Hi Laura. Please could you help me with this question. I have no idea what to do?
