Help your students prepare for their Maths GCSE with this free exact trig values worksheet of 22 questions and answers
The sin, cos and tan of certain angles are exact values rather than decimals. The exact trigonometric values of sin, cos and tan are:
Knowing the exact values of sin, cos and tan allows us to use the trigonometric functions without using a calculator for certain angles.
These values can be found by applying the trigonometric ratios of sin, cos and tan to two special triangles:
For example, using the trig ratio sin(x) = opposite/hypotenuse we get sin(45) = 1/square root of 2.
Applying each of the trig functions to these triangles will give the exact trig values for 30o, 45o and 600.
Looking forward, students can then progress to additional geometry worksheets, for example an area of compound shapes worksheet or how to work out perimeter worksheet.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
