Calculator Tips & Tricks for A-Level Maths/Further Maths ➕➖➗✖️ [fx-CG50 Graphics, fx-991EX Classwiz]

An overview of what I believe to be the best features of the CASIO fx-CG50 Graphics Calculator, and the CASIO fx-991EX Classwiz Calculator - all things that you can use for the exams!

I was going to include a feature that tells you the equations of tangents and normals, but this feature is disabled in ‘exam mode’ on the Graphics. You can still visualise tangents and normals, however, by pressing Sketch on the top functions when in Graph mode.

@TheCalculatorGuide has the best tutorial videos for how to actually use different features of the calculator - make sure you check them out and subscribe!

I too am an advocate of the double calculator approach

[haiqing]

Thanks, very useful! You are the best maths tutor I have ever seen in the UK.

[snaapssnaaps]

Thank you for making this video, I've heard that by making the most out of your calculator can really give you an advantage in exams!

[cjjk]

Definitely your most important video. Fantastic

[nathanhawey]

Oh waited this my man, I will watch it later thank u!

[TechJason]

Just got the CG50! Super useful video thanks!

[TheCalculatorGuide]

Superb video Mr. Bicen with a lot of great information for A-level students. Thanks for the shoutout too!

[davidhill]

Thanks so much for your youtube maths. Its amazing that you seem to make it a lot easier for people who struggle with maths like me.

Hi Mr Bicen I just wanted to say thank you for making these videos, especially your lessons. I am self-teaching Maths and Further Maths in Year 11 right now to take my exams next year independently, and your videos make me feel more secure as it feels like I have a structured learning environment to fall back on if I get stuck. Thank you again :) Do you have plans at all on uploading lessons for Further Maths: Further Pure 1 (the option topic) or do you not teach that? Either way, your content is great and so are you!

[shabbabassi]

Thanks for the video bro appreciate the help

[AG-bqzd]

Thank youuu this is a topic I’ve been wanting you to cover for the longest time!! Can’t wait to sit down and watch later!

[copiryte]

this would be my list for uses of calculator to check answers for core pure 1:

chapter 1: your calulator does complex number arithmetic so just substitute to check.
solving a polynomial always find out by the roots before you try to solve we it to sense check it (remember though that list all your working like "two of the roots must be complex" because...)


chapter 2 argand diagram

slightly trickier to use calculators but try solving same ploting polar. coordinates visulaise the scenario using Cartesian coordinates.
when solving a nonlinear simultaneous equations always remember to substitute then use Solve N to check.

chapter 3 just check using the actual summation notation solver
and just substitute your values to check.
chapter 4 just find the actual roots by solver and check if they follow the rules in the question.

chapter 5 use the built in integration tool to check and substitute
chapter 6 and 7 just use in built matrix tools questions with variables just sub in values qnd sub in the same values to see if they match. Questions with 0 det simultaneous equations use the simultaneous equations solver to check how many solutions.

8 actually check values to see if the proof seems reasonable

9 If you want to do dot product do two vectors but do the transpose of the first vector then use matrix multiplication.
for cross product just do the det of 3 separate matrices.

Hi sir, thank you for these videos they have helped me so much! Please could you make a video on all the proofs you need to memorise for A level Edexcel maths, for example the sequences proofs? Thank you ☺️

[AT-njkr]

Thank you for doing this I really appreciate it 😂😃

[akashif._]

thank you for doing this and other types of videos, your videos are good

[mrsujadmaths]

lol brilliant effort you've put in to these videos keep going from strength to strength!

[t.o]

omg thank you!! you litereally read my mind i was gonna ask for this video lol

[harryhazard]

Hi sir if your struggling for any video ideas, I would find it very useful if you went through the textbooks and picked the hardest questions from each topic and worked through them thanks for your videos

[jakescaife]

Mr Bicen, if you get the chance could you please do a basic list of all the main areas you expect to be on questions 1-8/9 on the upcoming papers, basically just to prioritise revision on areas for the easier questions to achieve a definite C. Thank you

[vitaszernys]

I assumed it was 44mins for one calculator. Thank god it wasn't.
31:10 is the "normal" calculator (Classwiz) that you probably have
