Question

I am a little bit confused of how to obtain ratios from the unit cycle plz help

Answer 1

Whats the problem?

Answer 2

you have the unit circle with you ?

there will be angles and their corresponding co-ordinates.
like at angle, 45 or pi/4
the co-ordinates are (1/sqrt 2, 1/sqrt 2)
the x co-ordinate represents cos value of that angle
so, cos 45 = 1/sqrt 2
the y - value represents sin value of the angle
so sin 45 = 1/sqrt 2
you can also find other ratios from this
