Exact Trigonometric Values Gcse Maths Beyond Revision For your non calculator paper, there are some trigonometric values you need to know. these are known as the exact trigonometric values. the values you need to know are below, along with some helpful hints to help you remember them. you will also be shown how to work them out quickly in an exam if you are unable to remember them. using the unit. Show step. we need the exact value of sin45sin45 and tan60tan60. substitute the exact trig value into the required formula equation. show step. as sin45 = √2 2sin45 = 22 and tan60 = √3tan60 = 3, substituting these values into the equation, we have sin45 tan60 = √2 2 √3.sin45 tan 60 = 22 3. solve the equation.

Exact Trigonometric Values Gcse Maths Beyond Revision Learners will need to remember the exact trigonometric values shown below. they may find it easier to memorise the values or to define them from using other methods set out in the worksheet. θ 0° 30° 45° 60° 90°. sin (θ) 0 1 2 1 √2 or √2 2 √3 2 1. cos (θ) 1 √3 2 1 √2 or √2 2 1 2 0. tan (θ) 0 1 √3 or √3 3 1 √3 undefined. Using an equilateral triangle of side length 2 units, derive the exact values for the sine, cosine and tangent of 60° and 30°. sketch the triangle and create two right angled triangles by drawing the line of symmetry through the middle. use pythagoras' theorem to find the vertical height of the triangle. use sohcahtoa to find the trig ratios.
