Best ResponseYou've already chosen the best response.0well what do you know about those 2 functions in relation to each other

Best ResponseYou've already chosen the best response.0That's all it says on my homework paper, 'Use the appropriate reciprocal identity to find each function value.'

Best ResponseYou've already chosen the best response.0ya, but you didn't answer my question. you have soh cah toa. and the three inverse functions. which one is the inverse of sin

Best ResponseYou've already chosen the best response.0or maybe call it reciprocal? im not good at my language

anonymous

Best ResponseYou've already chosen the best response.0As far as I know it's reciprocal is csc=1/sin

Best ResponseYou've already chosen the best response.0alright then. what do you think the answer is

anonymous

Best ResponseYou've already chosen the best response.0I just have different ones like tanθ if cotθ=sqrt6/2 and I don't really understand

Best ResponseYou've already chosen the best response.0so your correct on this problem. do you know about radians yet for the other problems?

anonymous

Best ResponseYou've already chosen the best response.0WHat do you mean radians?

anonymous

Best ResponseYou've already chosen the best response.0and cot and tan are reciprocals as well. radiansdegrees. have you now done the unit circle yet?

anonymous

Best ResponseYou've already chosen the best response.0I don't recall so I am going to have to say no.

anonymous

Best ResponseYou've already chosen the best response.0well. hmm.. you need to learn about radians and degrees for trigonometry. but just to avoid that. remember that cot and tan are reciprocal identities as well. but you cant have a radical in the denominator

Best ResponseYou've already chosen the best response.0Yea, so how would I go on in doing that? I am in Precal if that makes a difference.

Best ResponseYou've already chosen the best response.0http://tutorial.math.lamar.edu/cheat_table.aspx print that off. it will do wonders for your trig identities. do you know how to rationalize the denominator

anonymous

Best ResponseYou've already chosen the best response.0tell me where you are at on the second problem

anonymous

Best ResponseYou've already chosen the best response.0All I can really understand is that tanθ= 1/sqrt6/2, but I don't know how to make it like without the sqrt in the denominator.

Best ResponseYou've already chosen the best response.0hm. what is the reciprocal of \[\frac{ \sqrt{6} }{ 2 }\]

anonymous

Best ResponseYou've already chosen the best response.0Umm tbh I'm not really sure :/

Best ResponseYou've already chosen the best response.0You multiply the numerator and denominator by your square rooted number to get rid of the root in the bottom, this is known as rationalizing it. Here is an example dw:1385354774715:dw

Best ResponseYou've already chosen the best response.0Oh ok I see so now I have to get the reciprocal.

anonymous

Best ResponseYou've already chosen the best response.0but it would be 6/2sqrt2

anonymous

Best ResponseYou've already chosen the best response.0reciprocal would be flipping your fraction like if you were dividing by fractions \[\frac{ 2 }{ \sqrt{6} }\] this is the reciprocal of my above fraction. and when you multiply 2 square roots like that above you would have 2 not 1

anonymous

Best ResponseYou've already chosen the best response.0so if you multiply this \[\frac{ 2(\sqrt{6)} }{ \sqrt{6}*\sqrt{6} }\] that is how you rationalize the denominator

anonymous

Best ResponseYou've already chosen the best response.0oh I see now, so then the answer is 2/√6, I don't have to rationalize anything I believe.

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0keeping in mind \[\sqrt{6}*\sqrt{6}=\sqrt{36}\]

anonymous

Best ResponseYou've already chosen the best response.0Ok, thanks a lot! really appreciate the help!

anonymous

Best ResponseYou've already chosen the best response.0you cant have square roots in the denominator. you have to rationalize it like I did in the above step

anonymous

Best ResponseYou've already chosen the best response.0see how I multiplied the top and bottom by \[\sqrt{6}\]

anonymous

Best ResponseYou've already chosen the best response.0Some teacher dont require rationalizing, but it is generally required, so if it wasn't required you would be right. From your answer above, look to simplify it !

anonymous

Best ResponseYou've already chosen the best response.0looks like you can simplify it a little more think of it as \[\frac{ 2 }{ 6 }*\sqrt{6}\]
