The following assignment will be graded by your instructor 1

The following assignment will be graded by your instructor:

1) What are the solutions of sin (x – ) + 2 = 1 in [0, 2)?

2) Use your calculator to find arcsin (sin (150 degrees) ). Why didn’t the calculator say 150 degrees?

3) What are the four solutions of x⁴ = 1?

You should write about what parts of the text were the most difficult to read, and to identify how many times a passage was read before some understanding was achieved. Mathematical writing is often not immediately understood, and takes time and thought before comprehension.

Solution

The part arc sin (sin (150 degrees) ) was difficult to read. This part had to be read twice before some understanding was achieved.
