Best ResponseYou've already chosen the best response.0dw:1349413466539:dw the ratios mentioned are positive in that quadrant.

Best ResponseYou've already chosen the best response.1oh so its in quadrant 1?

hartnn

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

Best ResponseYou've already chosen the best response.0from the diagram, in which quadrant you find tan to be positive ?

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

Best ResponseYou've already chosen the best response.0cos (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?

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

Best ResponseYou've already chosen the best response.0that 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 ?

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

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

hartnn

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

Best ResponseYou've already chosen the best response.1so is tan ever negative then cat is too

hartnn

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

SugarRainbow

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

hartnn

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

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

SugarRainbow

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

hartnn

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

Best ResponseYou've already chosen the best response.1okay then what about sec

SugarRainbow

Best ResponseYou've already chosen the best response.1to akash_809 I see wat you did there

hartnn

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

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

Best ResponseYou've already chosen the best response.1okay now can we do the next question

hartnn

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

Best ResponseYou've already chosen the best response.1yeah 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)

Best ResponseYou've already chosen the best response.1okay next question how would you find exact value of 5pi/3?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.05pi/3 ? in degrees ? or some ratio of 5pi/3 ? like sin 5pi/3

SugarRainbow

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

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

Best ResponseYou've already chosen the best response.0i 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

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

hartnn

Best ResponseYou've already chosen the best response.0umm,  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

Best ResponseYou've already chosen the best response.1okay last question how would you horizontally shift y=4 sin (beta80)

SugarRainbow

Best ResponseYou've already chosen the best response.1oh 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...

Best ResponseYou've already chosen the best response.11/sqrt10 then multiply by sqrt 10 to get 1sqrt10/10?
