Draw a right angled triangle, label one angle as β\beta

Label the opposite and adjacent sides to give the required tan⁡β\tan \beta

Use Pythagoras to find the hypotenuse

Find cos⁡β\cos \beta and sin⁡β\sin \beta

Well there would be infinite ways but I would suggest using 222\sqrt{2} and 1 as the easiest version
