Unit S Concept 7 Assessment #4



What is this video about?

• This video is about solving equations with half-angle formulas. The video demonstrates step by step information on how to solve and what formulas were used in order to complete this problem.

What does the viewer need to pay attention to in order to understand the concept?

• The viewer needs to pay attention and notice that in order to solve these problems they need to understand the information learned in math prior to this concept because it is essential to solving the problem. There will be references to the unit circle as well as formulas used when solving identities. In addition, everything in the video that is in purple and in red are used to identify the formulas and the steps that were used in order to solve the problem.

Student Video #4 Unit S Concept 3 Question #1




What is this video about?

• This video teaches how to solve problems using power-reducing formulas. It demonstrates the goals that should be achieved when using power-reducing formulas as well as what steps to take to solve the problems. In addition, it shows each step in detail explaining why things are done and how they are done to solve the problem.

What does the viewer need to pay attention to in order to understand the concept?

• The viewer needs to pay close attention to why the steps that are taken are being done. It is important to understand that our first goal is to get everything reduced to the power of one and from there reduce as further as possible. Also, understand what can be combined and what can't and the reasons behind that.

Student Video #3 Unit H Concept 7

• What is this video about?

This video is about Unit H Concept 7 where we work step by step to find the logs when we are given approximations. 

• What does the viewer need to pay special attention to in order to understand the concept?

The viewer needs to pay attention to the extra clue that we demonstrate in the video because it sometimes helps to get to our answer when finding logs. They need to understand what we do and why we do by watching the steps in how we solve it.






What is this video about?
 The video is about finding all the possible zeroes that are in the equation and it demonstrates step by step what you need to know to find a zero.

What does the viewer need to pay special attention to in order to understand the concept?
The viewer needs to keep special attention that the zeroes that they get as an answer is one of the possibilities as a potential zero. If it is one of the zeroes then you know you are doing the problem right.
