Section 4.8

This is our last question for this section.
Note: Moving forward less questions per section will be the focus. The goal is to understand the concept behind each topic. Once the concept is understood, answering questions becomes a lot easier, I think. You say?

Part (a)

Is there am easier way to express the answer for part (c)?

We now move on to Chapter 5.

way to express the answer for part (c)

t = (π n)/16 - π/32, n element Z
substitute n=1
t = (π*1)/16 - π/32
t = π/16 - π/32
t = 2π/32 - π/32
t=π/32
t≈0.09817477

Is part (b) correct?

We move on to Chapter 5 aka Analytic Trigonometry. In Chapter 5, we tackle trigonometric identities and yes, more word problems. By the way, I love trigonometric identities.

Remember: There will be less questions moving forward to focus more on the concept behind each topic. In fact, I think it was you who stated a few weeks ago that learning the concept or idea leads to answering more questions correctly. So, I guess this is what we'll do.

It is my hope that you will stick around as we make our way to Calculus l. I expect to be in the James Stewart calculus textbook by early April or late March. Let's see what happens. Life is unpredictable.

part (b) is correct

Ok. It looks like our Section 4.8 has come to an end. Of course, there is chapter review Section, which I have no time for.
