Lesson 5 in our new Tom Rocks Maths Appeal YouTube series is OUT NOW!
Team Maths Appeal (me and Bobby Seagull) have joined forces with the University of Oxford mathematician, Dr Tom Crawford (aka Tom Rocks Maths) to explore and teach topics from the GCSE Maths syllabus. We aim to show the world that maths is accessible to everyone!
In this episode you will learn the values for Cos, Sin and Tan at the important angles of 0, 30, 45, 60 and 90 degrees. Tom introduces the topic via the graphs of sin and cos, I derive the values for sin and cos using Pythagoras’ Theorem and Trigonometry, and Bobby explains how to calculate the values for Tan. Direct links to each part below.
Tom (Graphs of Sin and Cos): 0:00
Susan (Pythagoras’ Theorem and trigonometry): 6:09
Bobby (Tan values): 12:48
