As a first timer to using Unity 2017, in this tutorial we will show you how to make a spinning coin.
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.
In this video we talk about how to shift the curve y=sin(x) to the right or to the left, by adding a constant inside the bracket e.g. by writing y=sin(x+c) this will move the curve to the left by c units. This only works when coefficient of x is 1. In the next video we …
In this tutorial we show you guys how to shift the graph up and down by adding or subtracting a constant at the end of the equation i.e. y=sin(x)+c
