thanks, anita;) i have started to understand the unit circle much better and also trigonometric functions of the circle, but i’m still unsure about reference angels that are greater than 360 degrees, but i’m not too worried b/c andrew is really god at expaling things and i’m sure he’ll help. we both enjoy learning about circles and pre-calc. i realize the colors of the unit circle, although they helped me focus in class when the teacher was going over it, when i’m studying, the colors overlap and blur together and i’m not sure which angle or coordinate is which. but andrew was great yesterday, he went online and printed out a blank unit circle and he quizzed me on it, i did well with the coordinates, but not too well with the angles in radians and degrees (i only made it 1/4 of circle). he was quite helpful and was explaining how to get the measures of the angles. i think after more practice, i will memorize the circle;)
