Statistics is the branch of mathematics concerned with the collection, interpretation and analysis of data. Statistics is often defined as “the science of making decisions in the face of uncertainty“. Data is the name given to the collection of information usually expressed in numerical form. Data handling involves:      1. Collecting data for a particular purpose. 2.  Sorting data. 3.  Representing[Read More…]

Science in Maths!

Albert Einstein, supposedly, once said that compound interest was the greatest force in the universe. Compound interest can either work for you (for example when you save) or against you (when you owe money.)

Plan properly and cut costs!

With Linear programming we can plan the efficient allocation, and use of, resources. Linear programming was first developed in 1947 by George b. Danzig, an employee of the United States Air Force to solve a particular real-life problem.  He used inequalities to model how the Air Force allocated supplies to its staff.  Then he used the linear programming method to[Read More…]

Here’s the answer!!

Here’s the answer!!

I promised to provide the answers to the questions in the previous blog. In question a) we need the height of the arch where the bridge , therefore we will substitute the x = 100 into the equation. So, 100metres away from the pylon, the bridge is 84,84 metres high.     For b) you you need to put H(x)[Read More…]

Balancing our way in algebra… and geometry!

Balancing our way in algebra… and geometry!

Balancing sounds like fun! The last two weeks we have learned how to solve problems by forming and balancing special number sentences called equations.We solved equations with or without brackets We have been looking at solving equations by inspection and by balancing the two sides. A GOLDEN RULE:When solving a problem… always read it through once or twice, to make[Read More…]

Calculus!!

Calculus!!

“Calculus is probably one of the greatest creations of human thought.  It has become a powerful tool for solving important problems in the world of mathematics and science.”  [Mathematics text and work book: Mind action series page 208] Calculus was invented in the seventeenth century by the great mathematicians Newton, Leibniz and Cauchy as a means of investigating problems that[Read More…]

MATHS IS COOL ..SCIENCE IS GREAT…

Okay..now listen .Nobody gets in here without answering the following question: ‘A train leaves Philadelphia at 1:00pm.  It’s travelling at 65 kilometres per hour.  Another train leaves Denver at 4:00… Say, you need some paper?’ Math phobic’s nightmare!

It goes round and round!!

It goes round and round!!

Yes, we are talking CIRCLES!  Not in circles, but about circles. According to the Oxford dictionary: “a perfectly round plane figure, line enclosing it; roundish enclosure, ring …” In Mathematics we are interested in the circumference, radius, midpoint and area.  To be able to calculate most of these, we need the radius. In grade 12 we take it a step[Read More…]

Analytical or Coordinate Geometry?  It does not matter which name you give it!  It deals with the study of geometry using the Cartesian Number Plane and is an algebraic approach to the study of geometry.  Analytical, or if you prefer, Coordinate Geometry “is widely used in physics and engineering, and is the foundation of most modern fields of geometry including[Read More…]

It is so EASY!!

It is so EASY!!

I got the letter in the post inviting me to take out a loan for R100 000.  It seems to be so  easy, you just dial 0861 ……., listen for 20 minutes and within 48 hours you can start spending! BUT if you are a Grade 12 Mathematics learner, you should think twice!!  Nothing comes cheap.  If you take the[Read More…]
