Aiming to Improve Your Maths Grade? Reduce Maths Stress and Anxiety by Using These Ideas.
This video is from a series of three where I give a summary of all the non-mathematical top tips that I give students to help them get as many marks as possible in their maths exams. It describes techniques you can use to manage maths anxiety when taking a maths exam.
The main features are; how to deal with negative self talk, managing nerves, suggestions on how to boost motivation and the importance of noticing successes.
This video was originally intended for GCSE resit students but I have found that it is just as relevent for all GCSE and A level students too.
The other two videos in the set talk about how to revise for a maths exam and how to strategically prepare for your maths exam.

You can use this method with grouped data too by first finding the midpoint of the class intervals and then using that as x
Thank you for saving me ❤️🙏 My test is tomorrow

Thank you !
is it possible to solve a quadratic trig equation eg: 5tan^2x - 38tanx -16 = 0? (using this function)
In this case you'd have to let y=tanx to get 5y^2-38y-16=0 which would get you the two values for y. You then would have to solve for x in your given range.
Thank you😊
Thanks please don't ever stop making these
WooW I wasn't able to see that button on my calculator👨🦯
Thanks. Love from bangladesh❤❤❤❤❤
Good job
thanks for explaining
Thanks this will help me save the world🗿
Thank youuuu
why is it not 120 degrees
You are using the outer scale because it starts from 0 degrees at one side of the angle
Don't like calculators where you need to go to different options to get a simple function
I agree! Sometimes it's difficult to find the simple function in the first place too - hence the video. Hope it helped
Helen ilysm ur my fave !😍😘😍
Thank you so much 🥰
Format..decimal
Thank you again... Watching this for the second time
Thanks sis ❤
But In Our exams this types of calculator are not allowed to use.😅
Which exams do you think that they aren't allowed in?
@@helenmathstutor Indian Exam of Chartered Accountants
now what about a square
Exams in an hour am i cooked
Thanks for the help❤ I was confused with this new Casio calculator
What if the first x was power 3 and the second is power 2 ik that u choose tte third function but it gives me 4 places to put the answers do u have any solution for that Ty btw for that torurial
I only have 3 numbers
If the leading power of x is 3, then you are trying to solve a cubic equation. A cubic equation has the form ax^3 + bx^2 + cx +d = 0. You would need to select degree 3 to tell the calculator its a cubic you're trying to solve. It will then ask you to input the values of the coefficients a,b,c and d.
Nice any more videos on this calculator
Thank you! I'm building up the playlist of fx-991CW videos...
How i can use Casio fx-991CW, changing decimals to fraction? How to change decimals to degrees? and how to use the shift "+" function?
Do you mean how to compare an angle to a full circle with the answer given in decimal form? If so then given an angle of say 75 degrees, it would be 75/360 = 0.208
@@helenmathstutor I able to find how to use it of Degree, Minute, Sec. But another thing is from decimal to fraction, how to do it?
Thank you ma’am ❤
Thank you !
Thank you!
thanks
I ducking love this video, no bullshit introduction no subscribe and just getting to the point. thank you pleas make more

Cheer~~~an instrument for measuring angles, typically in the form of a flat semicircle marked with degrees along the curved edge.😊
Sister,, can i do double differentiation by 991 cw?
This calculator gives a numerical value for the first order derivative at a specific point - it doesn't support symbolic differentiation. So it can't provide a second order derivative since it doesn't give the first order derivative as a function of x.
THANK YOU!
Thank you ❤
Sigma balls
This video really helps me in 2024 Thank you ❤
Ate that up
Iam getting infinite solution error, how to make it correct.
If the calculator isn't giving you finite values a likely reason is that the simultaneous equations you're trying to solve are for a pair of parallel lines. Parallel lines meet at infinity hence your infinite solution error. Hope this helps.
