Im very confused on how to get the sides of the unit circle. By that i mean like sin/cos of 0,90,180,360... I can get the others by this logic for example:
For example if it asks me
- Sin 150: I would first see the quadrant.. Its Quadrant II so it means Sin is the only one positive... Ok so i know its positive, and next i would know that sin is always the hieght so according to that picture it is 1/2.. So i would know the sin of 150 is 1/2...
I can do that for every angle presented on the picture exept the 0,90,180,360... How do you possible calculate the sin/cos for the angles i just mentioned. Thankyou
