In this second post on Trig we will look at sector area and arc length. You will need to be familiar with radians to fully understand this. As always try the questions, look at the videos if needed and ask at our Facebook Support Group if needed.
Today we will look at the sine and cosine rule and triangle area. These should be familiar to you from GCSE but you may find the questions aren’t asked so nicely. Don’t forget to have your calculator correctly in radians or degrees.
Try the questions below. If you are stuck then take a look at the video or if you are a New College Student you can also ask in our Facebook Support Group.
