I am learning about the unit circle and I am a bit confused.
So, I have my circle drawn with radius 1 and I sketched a right angled triangle inside it so that the hypothenuse has a length of 1.
I think what is making me confused is the meaning of sine, cosine and tangent.
They are functions of an angle x that enable me to find the length of a side of a triangle provided I have an angle and one length? In this case, with the hypothenuse being 1, it will be equal to the function of the angle? Is that right?
And, finally in the case of tangent for example, I am not finding the length am I?
Thanks,
