dw:1349413466539:dw the ratios mentioned are positive in that quadrant.

oh so its in quadrant 1?
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
in quadrant 1 ALL are positive, your question requires, tan to be negaive, so its not in 1st quadrant

*sorry, cos to be negative

from the diagram, in which quadrant you find tan to be positive ?
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
uh tan is positive in idk i looking at my unit circle and where tan is on your diagram its negative unless its in q1

cos (beta) < 0 means beta is in QII, QIII tan (beta) > 0 means beta is in QIII, QI where does beta have to be to meet these two requirements?

SugarRainbowBest ResponseYou've already chosen the best response.1
but tan is x right? wait can i even reate this to thisdw:1349413939970:dw

hartnnBest ResponseYou've already chosen the best response.0
that circle has co=ordinates of cos and sine so now you know the signs of cos and sine can u find out sign of tan using that, in each quadrant ?
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
oh wait tan = sin/cos/45 in which yes that part is positive so its in q3!!!!!

SugarRainbowBest ResponseYou've already chosen the best response.1
hey just for note taking is the cot negative then?
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
when tan is positive cot = 1/ tan is also positive

SugarRainbowBest ResponseYou've already chosen the best response.1
so is tan ever negative then cat is too
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
tan is negative when only one of sin or cos is negative, that is in 2nd and 4th quadrant
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
and in the all part they're alll only positive right
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
yes. in 1st quadrant all ratios are positive

just a way, i used to remember above diagaram, Add , Sugar, To ,Coffe...
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
okay then in q2 and q4 then cot is  yes?
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
okay then sin is + in q2 and  in q 3 and 4?
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
yes, you are reading it correctly :)

SugarRainbowBest ResponseYou've already chosen the best response.1
okay then what about sec
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
to akash_809 I see wat you did there
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
since sec = 1/cos sign of sec is same as sign of cos everywhere

hartnnBest ResponseYou've already chosen the best response.0
csc x =1/ sin x sign of csc is same as sign of sin everywhere

SugarRainbowBest ResponseYou've already chosen the best response.1
oh wait cos is + in q4 and  in q 2 and 3 correct?
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
okay now can we do the next question
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
u can use Add sugar to coffee or All silver tea cups to remember that diagram. or you could make one on your own.

hartnnBest ResponseYou've already chosen the best response.0
like add sugarrainbow to castle
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
yeah i gots it now the all suckers take crap is the ones that are the only ones positive in their quadrant (except q1 where they're all positive)

okay next question how would you find exact value of 5pi/3?
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
5pi/3 ? in degrees ? or some ratio of 5pi/3 ? like sin 5pi/3
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
umm it just says "the exact value of csc (5pi/3) (oops i guess i forgot the ratio part sorry)
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
u need to use some of trignometry identities. first can u find sin (5pi/3) because csc =1/ sin

i need help . The image below shows two parallel lines cut by a transversal. What is the value of a? two vertical lines cut with a transversal, the angle below and to the right of where the transversal intersects the left line is labeled 2 a plus 3 degrees, and the angle above and to the right of where the transversal intersects the right line is labeled a degrees

SugarRainbowBest ResponseYou've already chosen the best response.1
yes its square root 3/2 and you would multiply by radical 3 to get 2sqrt3/3!!!!
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
umm,  root 3 / 2 ... why do u need to multiply by radical ? sin 5pi/6 =  root 3 /2 csc 5 pi/6 = 2/ root 3 here, you will multiply by radical 3 to get csc 5pi/6 = 2sqrt3/3
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
yeah that's what i got?
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
then you are correct :)

okay last question how would you horizontally shift y=4 sin (beta80)
 one year ago

SugarRainbowBest ResponseYou've already chosen the best response.1
oh yeah and this question says determine the exact values of the 6 trigonometric functios of an angle in standard position whose terminal side passes through the point (1,3) and for tan i got 1/3 and cot i got 3/3 and she said its wrong so was i supposed to do...

1/sqrt10 then multiply by sqrt 10 to get 1sqrt10/10?
