You can do absolute value of the vector for magnitude

In the exponential equation,after getting my first answer,when I press equal to it keeps showing can't solve

Is this statistics?

17:52 how do you go back and find the dot product? i bought the calculator and i want to know how to use this one but i am very confuse though i really learned from it.

For q2, how did you know to write cos in terms of sin, and not sin in terms of cos??

praying that this is higher cause what

question 20, there are much easier way to do it, since each digits is prime, so in the number 2,3,5,7, you choose any two number,for example 75 not prime, then 73 is. choose smallest two number 23, 73-23=50

I'm trying to follow the Vector problem and after entering the values for B, pressing the down cursor I'm not getting the menu selection that you get to select the dot value, when I press down arrow, I get a blank screen? I'm using a brand new fx-991EX

Great video man, thanks

Try to solve the one at 16:00 always gives me the wrong answer either by hand either using radians or degrees. I can't understand why is it 10.223.

For b) you could also multiply the first digit by the last digit and add that. 104 is therefore also a valid answer.

CAN THIS CALC DO (SINE SQUARE OF SOME NUMBER!) SAY sine square 14 + sine spuare 22 =?

Can you raise a matrix to a power higher than 3. Doesn't seem to work when i use the power button next to the the square and cube button

For the first question, wasn't the question asking for the number of tiles? 2n is the number of sides right? So why would the number of sides = the number of tiles.

I nearly got the second one! I'm only in year nine and it was the scale factor for finding CD.

Thank you very much for all your time and trouble spent doing the equations by hand just so you could compare the answers! Thank you for making this video, it has been a great help to me!

16:14 is the wrong answer

thanks for the video, it was usefull

More numbers.

Thank you, a very informative and helpful video!

4:00. Hi, I'm confused about the +9 in the quadratic equation, shouldn't it be -9 as you need take 9 from both side to get 0? Thanks!

Really appreciate your videos on ocr maths papers, it has helped my son as he was struggling with aspects of understanding maths statistics. I hope to see more videos of yours. Thank you 😊

bruh this paper ended up being my mock, thank god i watched it.

My daughter asks what the steps are to get from xy-x = y went to x(y-1) = y on question 16...

How on earth did you go back to the vector menu

15:08 shouldn't you have multiplied the 1/2 onto 32/18 which gets you 16/9, then you multiply it by 9 to get the correct unit?

Well explained buddy good job.

Thank you very much

Great video! Excellent explanation of your working and it greatly helped me!

great video loved it!

That x=0 @ 12:10, I assume that is supposed to be a guess.

Thank you for this explanation video 🙂

Can it solve the multiplication of 4 matrices together each matrix of dimension 4x4?

For the first question, we can see that for each trapezium, there is a 90-(83+1/3) = 20/3 turn. To complete a polygon the shape needs to turn for 360 degrees, so 360/(20/3) = 54. Done.

Could you do more of these walkthroughs for other papers cos they are really useful

Cristal Clear 👍

I don't even take Further Maths (Yet) 😭 But i'm the best in my class so they should move me up to the Further Maths Class (Update: I’m in top set and I’m doing further maths)

Hi, is any calculator in the market I can solve indefinite integrals ?? Cheers from Australia. keep up the good work. Thanks

is this better than fx85gtx

I’m starting further maths now and this is the same as normal gcsr( first 10mins), haven’t watch the rest

Hi, how can I write sin^2 with this calculator? Thanks.

Thanks for the tutorial it was very helpful, I got this calculator for A level maths.

You sold me on the calculator. It seems like it's got a ton of function

Another way for question 9: 50% of 18.3 is the same as 18.3% of 50 So you can just find 50% of 18.3 and times by 2

at 4:11 isn’t it suppose to be a negative 9 ?

I’ve seen very similar questions on A level maths papers. Quite difficult for only GCSE students.

Thank you❤️❤️...... it's really a hard job to choose the correct scientific calculator🔥🔥🔥🔥......Once you know about your requirements then it will be easy for you to choose the correct one....do not select by just seeing the price....I found a great collection of scientific calculators here @t ❤️❤️ check out this may help you in choosing the correct one based on your requirement.👍🔥🔥
