Week {11} – Precalculus 11 – {Inequalities}

Kiana on

My biggest mistake of the week was thinking that inequalities show the equation on the graph instead of the range for things, one i realised how to actually do it it was a lot easier. the steps for how to find the inqeualities are the following

  • Step 1: simplify the inequality so that it is in vertex form
  • Step 2: choose a test point and determine whether is will be true or false
  • Step 3: insert this test point into the original equation and determine whether it is true or false
  • step 4: depending on whether it is true or false, shade the inside or the outside of the parabola

Unit 1:

  • My strength from unit 1 was writing bhor and lewis diagrams. This was my strength because i could easily understand the concept of how many electron were supposed to go on each orbital. i could easily identify when to draw and ion instead of an atom. this helped me a lot in this unit since the next unit included a lot of lewis diagrams.
  • my goal: One thing i was not great at from this unit was writing out ionic formulas. i think this was my weakness because i got confused by all the rules and sometimes forgot some and then got the question wrong. I plan to get better at this by doing more practice questions at home since we hav to use them for the unit that we are doing right now. Another way i can get better is look through my notes whenever i get a question wrong.

Unit 2:

  • my strength: my strength was naming and drawing the vesper shape of a molecule. I was mostly good at this for simple molecules with only one base atom but I could also understand when there was more than one. I think i was good at this because i studied a lot to remember all of the different types of vesper shapes so my hard work payed off for this area of this unit.
  • my goal: my goal is to better understand bond diapoles and when a molecule is polarcovalent or non-polar covalent. I struggled a lot with this part because i had a hard time memorising the rules for each type of vesper shape. One way i can get better at this is look back on my notes and go through them thouroughly. After this i can practice with more questions and if i still dont understand i can go ask for additional help.

Unit 3:

  • my strength: my strength is finding the unitary rates of molar mass and finding how many moles are in some molecules. I can thouroughly show my work on this because i understand it. While we are still doing this unit, I can usually find the right answer and feel confident in most mole problems (relatevaly simple ones).
  • My goal: One thing i can work on is making sure i have the right amount of sig figs in my final answer and making sure i say the unit in my final answer because sometimes i forget to do this and it does not end up being right. One way i can get better at this is to (after i have finished all questions) double check my answer on all question and make sure i have put the right amount of sig figs and unitary rates. I can also check the sig figs at the beginning of the question so i don’t get confused later.

Week {5} – Precalculus 11 – {Solving radical Equations for division}

Kiana on

One mistake I made this week with solving radical equations is that at the end I did not simplify my equation so I kept getting my answers wrong. Once I finally realised i needed to simplify at the end, all my answers started making more sense

The steps are the following for solving radical equations for division:

Step 1: Find the conjugate for the denominator

Step 2: Multiply this conjugate to the denominator and the numerator

Step 3: Simplify where nessisary

 

Week 16- Math 10 – Solving Systems

Kiana on

To solve a system using substitution:

  • step 1: choose the most simple equation and isolate a variable on one side
  • step 2: insert this equation into the second euquation and solve for the variable
  • step 3: with the answer to this question you insert it into either one of the original equations and solve for the variable again
  • step 4: check your answer by inserting the variable answers into each equation

Week 10 – Math 10 – Equations for patterns

Kiana on

Equation for patterns

  • to make an equation for a pattern you need to:
  • 1. make an output and input chart for the pattern
  • 2. find the difference in the output numbers and start the euquation by forming: differencex
  • 3. times the difference by the input number and then subtract or minus to find the final part of the euqtion
  • (photo will explain better)

Week 9 – Math 10 – exponent laws

Kiana on

exponent laws

  • like terms— exponent stays the same but you add the coeffecient
  • multiplying bases— multilply bases, add exponents
  • dividing basas— subtract exponent, divide coefficient.
  • zero exponent— equals to one
  • negative exponent— to make a negative exponenet a possitive exponent find the reciprocal.
  • exponents with brackets— mulitiply exponents, power coeffitionts and constants
