#quadratic equations

Haruka is caught as a definitely unwilling participant of my mathematics calculations involving big but not that big numbers.

question for the americans! do you really have quadratic equations only in 10th grade??

Thursday 23rd September

Lessons today:

• maths from 9:15 until 12:45

• chemistry from 12:45 until 14:00

• maths from 15:30 until 16:30

I got into college at around 8:45 this morning so I could go the the helpzone to sort out some timetable clashes that have come up, then I grabbed a coffee and headed to my first maths class where we recapped some basic quadratic functions before moving on to some more advanced questions. In my chemistry class we were just working on some pretty simple equations to get re-aquainted with valency in terms of formulae. During my free period I sat in the library and read through some pages in my textbook on organelles before finishing up on my homework. Then in my last maths session of the day we did some more work on quadratics, this time we looked more into proof questions which was really interesting; also my teacher brought us all biscuits which was really nice!

Okay so call me a forgetful dork but I took notes while studying for the math section of the SAT with Khan Academy yesterday

Shoutout to @aredhel-of-gondolin for helping me study! If you tend to get distracted easily, I would recommend asking a friend to review with you. Personally, I feel a lot more focused when I study with other people, even if they’re watching tv and talking to me about it while I do work.

I used GoodNotes 5 to make these while I was studying. I love how Khan Academy tracks what you need to study more and gives you both videos to teach you and practice problems to make sure you understand. Sometimes, Sal’s way of teaching gets a bit confusing for me, so what I like to do is pause the video after he introduces the question and write down the important information. Then, if I understand it well enough at that point, I go ahead and try to solve it. If I get stuck or don’t know where to go, I play the video and stop right after he explains what I’ve been confused on. Then, I see if we got the same answer. If my answer is wrong, I go back and follow along to see where I got something wrong and try again from there.

I find that using a specific color to highlight important information/answers helps me remember it better when I’m reviewing! I thought this shade of blue was really cute as a preset highlighter but it didn’t have a matching pen color, so I went to “custom” and put in the same HEX code as the highlighter.

To give the titles a bit of a pop, I wrote them in black, selected and copied the text, pasted it at a slight angle from the original text, and changed the font to my highlighting color. This gives it a bit of a shadow effect and makes it really eye-catching. If you want to use white, go for it!

When you take notes to reference later, make sure you include all necessary information that helps your end result make sense. If you don’t know why your answer was wrong, always go back to the original question and make sure you’re answering exactly what the question asked.

Remember that your notes are for you. Don’t be afraid to write important information you might forget and need help remembering in the margins! I know I definitely did for a few of those pages.

Good luck!

Nature Of The Roots Of A Quadratic Equation The nature of the roots depends on the value of b2 – 4ac. bx2 – 4ac is called the discriminant of the quadratic equation ax2 + bx + c = 0 and is generally, denoted by D. ∴ D = b2 – 4ac If D > 0, i..e., b2 – …

If there was ever any doubt that I am a complete and utter nerd, I think the fact that I am practicing Matrices, Algebra, and Interest just for fun (and enjoying it!) means that all doubt has been thoroughly eradicated.

REBLOG TO SAVE A LIFE! 

This is how to factor quadratic  [trinomials] when ‘a’ is greater than 1 using  VERY less complicated than usual method. 

My friend who is a super super math whizz and very good at explaining math wasn’t even aware of this method- and was impressed. 

Good luck on finals!  <3

Thursday 7th October

Lessons today:

• maths from 9:15 until 12:45

• chemistry from 12:45 until 14:00

• maths from 15:30 until 16:30

My teacher didn't actually turn up to my 9:15 class so I took the opportunity to study quadratics before we move onto another topic. Then I met my friends to grab some lunch and we went over flashcards together for each of our subjects to focus on active recall. Very helpfully, my chemistry teacher didn't turn up either, so I headed to the library with some friends and we worked on our understanding of moles in more advanced chemical equations. My final lesson of the day was maths and my teacher did in fact show up this time! We did some revision of the topics we taught ourselves this morning and then did some exam questions before heading home. I plan to bring my flashcards with me to rehersals tonight to do some quiet revision in my breaks for my biology test tomorrow.
