Hey – if you have just started using this graphics calculator, you probably are having a hard time finding out how to clear the memory. You will be doing this a lot to get rid of unwanted settings. Eddie shows you how. You may also be requested to do this during an examination, so it’s …
There is a website that draws boxplots for you! After you’re done, you can copy and paste the boxplot to Word, Excel or where ever you want. A lot of your statistics math assignments at school may need you to draw a boxplot with your computer, to make it look professional. However, it’s quite difficult …
In this quick tutorial, we learn how to use Geogebra to differentiate and integrate functions. A good way to check your answers and to improve your understanding, as you will be able to see a graph and its derivatives or integrals on the same axis. A must-have tool for anyone learning calculus.
Finding the intersection between two lines manually can be a difficult and long process, and you can easily make mistakes. If you are able to use a Graphics Calculator in an exam, then you will definitely want to take advantage of the skill to be able to do it quickly. Here are the steps.
By following this tutorial, you get the TI-83 calculator emulator for your PC. Not sure if all functions will work – up to you to test it out.
Feel like a brain teaser? Try this trigonometric identity proof. Expect to struggle a bit! Thanks to one of my students who figured this out before me!
In this video I present two useful tips to help you prove trigonometric identities. I use a problem we’ve done previously but I prove it using a different method.
You are lucky if you can use a TI-84 for your exam, because you can now check the answer for the solution of any trig equation..
In this lesson we sum up everything we’ve learned so far with a practical modelling question involving temperature variations on a given day with respect to time in hours. Hopefully you guys don’t find it too difficult.
Trigonometric graphs lesson 7 – Horizontal translation followed by horizontal dilation, general form
Continuing from the last tutorial, we talk about what happens when we combine horizontal translation with horizontal dilation, and we give a general form for all periodic functions and talk about the effects of changing each constant/coefficient.
