Thank you for the feedback! I’m glad it helped!

@@JesusChristIsLord165 no worries! Good luck with your studies!

Hi Rav

That’s because it doesn’t exist in a practical sense. Odd nodes come in pairs.

Kia ora @Sibelius40! It really depends on your school as each internal can be a bit different from school to school, but usually Excellence involves making some modification or addition to the network to optimise an outcome. E.g. removing a path to make the network traversable for a race taking into consideration how the chosen path to remove may impact min/max distance. The other criteria is making sure that you’ve shown and communicated fully how you’ve calculated all 3 main skills, traversability, MST, and shortest path. This is best done through describing the algorithm you’ve used embedding the context of the question in your answer. The best person to ask though is your teacher as like I say each school may have slightly different requirements.

No worries! Glad it could be of use!

Can you be a little more specific so I can check?

I think it's correct

I agree

weirdo

16:31 Also around here for Area of triangle are you not supposed to also add SinA?. In my book it shows Area of a triangle 1/2bcSinA

Kia ora Nawa. 1/2abSinC and 1/2bcSinA are the same formula. The key is that they are both referring to a triangle where you have 2 sides and the angle between them. The capital letter in the formula is referring to the angle in the triangle, hence why I couldn’t use the 7 as the C in the area formula as it was side c not angle C. The letters refer to opposing sides and angles. Side c is opposite angle C.

@@mathsismaths1 Thank you 👍

I think it was asking for the perimeter of the new building, but I haven’t looked at in two years. Was there something about it that you disagreed with or was confused about what I did?

You’re not wrong, however the triangle you are referring to wouldn’t actually exist. The whole set up is mathematically incorrect and impossible, so neither solution would be correct. However, as this is a question in a Trig lesson I showed a trigonometric method of solving the question as opposed to a Circle Theorem method.

It is a small part of it in the Trig standard

Good luck! I hope it helped!

So do I! Good luck!

Sorry, I’m unsure of how you may have got this. I just double checked my value and it is accurate. If you tell me what you typed in your calculator I may be able to spot the error?

Awesome! Good work!

No worries! Good luck!

No worries!

On your calculator you should have got 7.986626657... as this is quite a long answer I rounded it to 2dp. This means we look at the number after the 2nd decimal place which is a 6. This tells us that we round our 2nd decimal place up from 8 to 9. Which gives us 7.99.

You may have your calculator set to Radians instead of Degrees. You can normally change this in the settings.

No worries! I’m glad you found it helpful!

if x is the real part and y is the coefficient of the imaginary part then yes that would get the same answer just with no showing of understanding.

Nimit nah you should be alright. But do it any way if you’re worried, you’re not going to lose marks for including it.
