Find the exact value cos? 39 45"=

Exact Value X

Tan(X)=3.4513

Any help would be appreciated im clueless on all of them problems

 

[Cooldude11]

can anyone tell me steps to solve these?

Please explain a little better.

What does \(\displaystyle 8sin^{2}{\theta}60\) mean?.

Is that \(\displaystyle 8sin^{2}(60)\)?. Or something else?.

 

[Cooldude11]

8sin?^2 60(degrees)

 

[galactus]

If it's 60 degrees, then why is that theta in there?. Do you mean \(\displaystyle 8sin^{2}(60)\)?.

I am done guessing.

You may have come to the wrong site for help.

On the freemathhelp boards, volunteers are here to guide students who already have a clue.

These boards are not an on-line classroom. We don't have time to start from scratch with most students (i.e., retyping weeks of instruction to provide prerequisite concepts or duplicate classroom or textbook lessons).

If you actually do have some clue, (and I think that you probably do), then show us what you already know about these exercises and explain what you're thinking.
