Best ResponseYou've already chosen the best response.1sin and tan are odd cos = even \[\large\rm sin(\theta)= \sin \theta\]\[\large\rm cos(\theta)= \cos \theta\]\[\large\rm Tan(\theta)=  Tan \theta\]

Best ResponseYou've already chosen the best response.0Honestly I have no idea. I am the worst with trigonometry. I don't understand it whatsoever

Best ResponseYou've already chosen the best response.1then u need to start it over \[\large\rm sin =\frac{ 1 }{ \csc }~~\cos=\frac{ 1 }{ \sec }~~~\tan=\frac{ 1 }{ \cot }=(\frac{ \sin }{ \cos })\] reciprocal of sin is 1/csc reciprocal of cos is 1/sec reciprocal of tan is 1/cost or you can say sin /cos csc=1/sin sec=1/cos cot=1/tan csc , sec and cot are reciprocal of sin , cos and tan

Best ResponseYou've already chosen the best response.1if sin =a/b then csc = b/a

Best ResponseYou've already chosen the best response.1so if sin is odd function then csc is odd or even ?

Best ResponseYou've already chosen the best response.1yes right that's how \[\huge\rm csc(120)=  \csc(120)\]

Best ResponseYou've already chosen the best response.0another way of looking at it is using the unit circle and fact that neg angle goes clockwise dw:1440006652430:dw

Best ResponseYou've already chosen the best response.0but I'm just not understanding how the negative comes out

Best ResponseYou've already chosen the best response.0sin refers to "yvalue" , on the circle sin(120) is the neg yvalue of sin(120)

Best ResponseYou've already chosen the best response.1\[\large\rm cos (45)= \cos(45)\] dw:1440007938868:dw xcoordinate represents cos function

Best ResponseYou've already chosen the best response.0wouldn't the cosine be negative too since it's in the 3rd quadrant ?

Best ResponseYou've already chosen the best response.1yeah i was just thinking about this .. cos is also negative in 2nd quadrant

Best ResponseYou've already chosen the best response.1for odd and oven just remember sin(x)= sin(x) cos(x)=cos(x) tan(x)= tan(x)

Best ResponseYou've already chosen the best response.0so it's not true for cos of theta ?

Nnesha

Best ResponseYou've already chosen the best response.1yes right cos (120) = cos(120)

Best ResponseYou've already chosen the best response.0how do I prove that ?

Best ResponseYou've already chosen the best response.0my question says to pick a value of theta and to test the theory

Best ResponseYou've already chosen the best response.1i guess because cos is negative in 2nd quadrant and in 3rd quadrant so negative times negative = positive even

Best ResponseYou've already chosen the best response.1:P i just know the basic stuff don't know how to explain better than that sorry
