Week 5, Entry 2
This week we worked with graphing tangent and cotangent functions. We learned how to graph the inverses of the functions. As we went over it in class, i pulled up a video to look over.

Week 5
Before given a lesson, my teacher gave us a packet to complete on graphing tangent functions. I had no idea what i was doing, so i used my Khan Academy app to look over a video that explained it more.
Helpful equations and terms:
tan x=sin x/cos x
undefined at 90 270

Week 3
19 January 2013
This past week we worked on graphing sine and cosine functions. In order to graph a sine and cosine function, the amplitude and period need to be identified. As my teacher explained how to find these things, i couldn't quite understand the concept. To gain a better understanding, I used my Khan Academy app. As i watched the video, there were examples done to help me and examples for me to complete. With the extra help, i was able to memorize the terms that were repeated and understand this concept in a better way.

This week we have been working on Triangular Trigonometry. With this section, the six different trig functions are used with right triangles. We started out by identifying the six trig functions in a right triangle. We also used the functions to solve for the missing sides and angles of triangles. I was able to go onto my Khan Academy: Trigonometry app and pull up a video that could help me with this lesson. The video provided equations such as:

Week 1
4 January 2013
From the four tools i use, i decided to reflect on Khan Academy.
Usually after I have a break from school, as we did, i tend to forget things taught before the break. With the help of this app i was able to catch up on the things i was previously taught. Such as converting radians to degrees and vice versa. I also tend to forget equations and terms. While in class, i was able to look up vocabulary and equations i hadn't quite memorized yet. I was able to access my app via iOS, but you can access it on Android.
