For my trig verification project I started using functions that i knew what change into something that would cancel somethings off. Which is why I chose to use Csc Tan and Sec Cot. Csc tan x cancels out to be 1 over cosine which is SecX and Sec CotX which cancels out to be 1 over sin which is Csc. For the numerators I made sure that one was equal to one because one is easy to work work and that the other one converted into just one function. Once I had the fractions simplified I created a common denominator by multiplying by Sec and then added the fractions to equal the right side. During this project I think i gained a better understanding of when I can cancel things out, I also think the extra practice of converting the trig functions and refreshing my memory on what things are equal to each other helped me become more confident with verification.

In this activity I learned about about how sin and cosin relate to the special triangles and I learned the importance of reference angles. In this activity the main thing I learned was the point of the unit circle. Since I have missed so many days of school the unit circle was not something I spent a lot of time focusing on but now I understand that the unit circle represents the x axis in the graph. I feel like I connected a lot of dots in during this activity. I think I connected the dots between radians and degrees without using the formula to convert them back and forth due to the usage of the unit circle in making the angel. I also think I connected the dots between the x and y axis and sin and cosin. The activity helped me understand the unit circle because before I didn't really pay much attention to it because it didn't seem very relevant to me. Finding the reference angle by using the unit circle helped me understand how the unit circle relates to the graph. I did not like that Mr. Cresswell did not affirm anything because I was scared we were doing it completely wrong.
