1. Let $$\theta$$ be an angle such that cos($$\theta$$) = -1/9 and 0 <= $$\theta$$ <= 2pi.

Assume that cos($$\theta$$/2) < 0 ; If

then what is a1 and a2? I have no clue how to do this.

2.  I don't understand how to get c and d. Can you help me?

Is there a typo ?

What happened to the -1/9 ?

Where did the 1/8 come from ?

The graph and related text is a separate question. It is not an attempt to answer the (first) question.  There are two (2) questions in the above post.

Twiistedwhyami, one reason for your twisted thought process is the lack of understanding for the necessary prerequisites for the math questions you presented. You should request a return to the prior, lower level math class. The teacher gave you passing marks to get rid of you. You didn’t really pass.

You should also request a return to your prior English class: your statement, “no typo, it came with the problem” is fragmented and lacks proper punctuation.

If you do not know how to communicate how do you expect to learn anything?

OK, that may explain the lack of capitalization, but that doesn’t account for the sentence fragment (first sentence lacks a predicate verb), the comma splice (the use of a comma to join two sentences together), and the lack of a period.

There are two (2) shift keys on most keyboards, allowing for convenient single-handed access. Also, toggling the “Caps Lock” key will produce uppercase letters.   This will help for capitalization and for shifted characters, such as quotes. However, only a review of the rules for standard English composition will help with sentence construction.

twistedwhyami,

Guest spent time looking at your question and asked you to verify the information.

Instead of thanking guest for their time and verifying the info, you just gave a thumbs down.

Do you really think this was an appropriate response.

Why would anyone bother trying to help you if you are abusvie in return.

fyi   I also think that you should verify the info in your question.
