Please Help!? Evaluate the following:

OpenStudy (anonymous):

yes ask

OpenStudy (anonymous):

1. \[Sin^{-1} \frac{ 1 }{ 2 }\]

OpenStudy (anonymous):

2. \[arccsc2\]

OpenStudy (anonymous):

3. \[\sin(Tan^{-1}3)\]

OpenStudy (anonymous):

4. \[\tan(Sin^{-1}(-\frac{ 5 }{ 13 }))\]

OpenStudy (anonymous):

for 3rd the tan value is?

OpenStudy (anonymous):

therefore for 3rd sin(71.56505118) Hope it helped

OpenStudy (anonymous):

How did you get that?

OpenStudy (anonymous):

using value of tan into 3 on the basic of what i do know

OpenStudy (anonymous):

Ok can you help with the others?

OpenStudy (anonymous):

fisrt did you got the 3rd one

OpenStudy (anonymous):

@B.Sanders YOU THERE

OpenStudy (anonymous):

@B.Sanders

OpenStudy (anonymous):

FOR THE 2ND ONE ITS arccsc 2 has the same meaning as 1/ sin x = 2 sinx =1/2 just keep in mind arc csc and arc sin they have same range so we will not lose any answer if sinx =1/2 then arc sin (1/2) =? arc sin (1/2) = 30 degree or Pi/6

OpenStudy (anonymous):

Yea I am here sorry.

OpenStudy (anonymous):

Okay I got that. Had to read it a few times but it makes sense now!

OpenStudy (anonymous):

SO YOU GOT ME

OpenStudy (anonymous):

Yep, so could it also be 5pi/6?

OpenStudy (anonymous):

WHY?

OpenStudy (anonymous):

@B.Sanders

OpenStudy (anonymous):

My teacher says there can be more then one answer. These are the answers A. \[\left\{ \pi/6, 5\pi/6 \right\}\] B. \[\pi/3\] C. \[\left\{ \pi/6\pm2\pi n, 5\pi/6\pm2\pi n \right\}\] D. \[\left\{ \pi/3\pm2\pi n, 5\pi/3\pm2\pi n \right\}\]

OpenStudy (anonymous):

ARE YOU IN A CLASS RIGHT NOW

OpenStudy (anonymous):

No

OpenStudy (anonymous):

yes your teacher is right too

OpenStudy (anonymous):

Okay that is what I thought, so it would be A? Correct?

OpenStudy (anonymous):

congrats its A

OpenStudy (anonymous):

Okay, thanks now how would I do 1 and 4?

OpenStudy (anonymous):

Sin^-1 is the same as arcSin right?

OpenStudy (anonymous):

@B.Sanders Can you do it yourself

OpenStudy (anonymous):

Yea I think I am getting it!

OpenStudy (anonymous):

you sure

OpenStudy (anonymous):

Yea.

OpenStudy (anonymous):

solve and show me the first one

OpenStudy (anonymous):

#1 I got 30 degrees?

OpenStudy (anonymous):

k show me your working

OpenStudy (anonymous):

I plugged it into my calculator.

OpenStudy (anonymous):

then why did i waste my time explaining 2 sums to you
