After working with the sine function graph, i learned how the unit circle relates to the sine function. Also, i realized that the graph is always repeating itself. In answer the last question, i saw that sinx=0 at 0,180, and 360 degrees. This would also be true when it is 0, pi, and 2pi radians.

I learned that the higher up you move the sin curve the bigger the number gets. That a sin curve when graphed on a cordinate plane is all squiglli

Three main things that i learned from the assessment were that the double amount of 360˚is the same radians. As well as the same coordinates. I also learned that the sin cos tan of 90 degrees is undefined

We learned the minimum value a graph can reach. We also learned that sine is the Y value, for example "y=sin (ø) when ø=0˚". To include we learned how to change radians into degrees, for example π/2=90.˚
I learned that the maximum value of the unit circle is 1, and the minimum is -1, for x and y.
theta is = 0 deg <_theta <_360 deg.
and a positive cycle is rotated counterclockwise, whereas a negative rotation is clockwise.
The three main components that I learned from the graph of a sine function are:
1) The x axis (y=0) houses not two but three degrees, (0,180,and 360).
2) The radius of the unit circle determines the y-value of the minimum and maximum points.
3) Reference angles are acute angles that are formed from a angle's terminal side and the horizontal axis (y=0)
I learned that 1 complete cycle is the same as -π 2 π.also, i better understand how to work with the unit circle and finding points on the graph using the sin of either the degree(˙)or the radians.
I learned that the maximum that sine can be is 1 and the minimum that sine can be is -1. When the sign is 1 pie or 180 degree's the sine will be 0 as well as at zero and 360 or 2 pie.

I realized that the graph is repetitive of its self and that it helps you to be able to understand how to figure if sin is equal to o -1 or 1 or in a range of numbers!!!

Dealing with cos was a liddle more trickier! because I had to use the graph for the x cordinate instead of the y cordinate. but yeah it helped me to distinguish between the different ways that y=cos thetta if thetta was equal to zero and all this other stuff!
Hey Ms. Lynch, to be totally honest, I really didn't understand what I was supposed to do. I didn't have a clue what I was doing, but I did try to figure it out. The light just didn't click on in me head. I just know I had to move the dot around the circle, find the answer for "sin" and thats about it.

I learned how the sine function relates to the graph a little better.
I learned that the maximum and the minimum of the unit circle are 1 and 0.
I also learned that the radius of the unit circle determines the y value of the maximum and minimum points.
Hey Ms. Lynch, the other comment that says "Diamond Princess" is mine. I forgot to put my name at the bottom.

I learned that with the sine function you use angles measured in degrees or angles but when no unit of measure is indicated the angle will be measured in degrees. another thing that I learned is that the minimum value reached by the graph is -1 and the maximum is 1. The points on a unit circle and the lengths of the side of the reference angle are important concepts is the last thing I learned in this lesson.
I learned that while on the graph the point may be proceeding farther positive or farther negative, the point on the unit circle continues to just go around and around. The number is indeed getting higher or lower but the representation of the growth or decay is better on the actually graph...
THIS CLASS RULES!!! :-)
With this website, i learned more about how to find sin n cos. I needed extra help but with the example that shows u how to work the problems step by step, i finally get all this!!! This is a great website to catch up on your work. Say if u didn't know how to find out sin with this website ull come ot knw you know alot!!!!
i learned what a complete cycle was.it's when you go from like (180,0) to (-180,0).its also equivalent to (π,0)to (-π,0).
Hey Ms Lynch...i learned the factors of the cosine and how it relates to the graphs. I learned about the minimum point and how its the lowest point reached on the graph.
i put 2 comments on about the sine curve thingy so just telling you it says annonymous but it wont put my name for some reason so...

i learned that the sine function is in relation with the graph. I also learned that the maximum and minimum value of the unit circle 1 and 0.I also learned that clockwise on the unit circle is positive and counter clockwise is negative. (Sabrina Rivera)

I learned that for sine on the unit circle, the highest point you can reach is 1 and the lowest point you can reach is negative one. All other coordinates fall in between.
