Best ResponseYou've already chosen the best response.0@freckles I love you <3 just so you know xD I've gotten to sec(theta)=1/2 and sec(theta)=1

Best ResponseYou've already chosen the best response.0But on the unit circle secant never = 1/2 and it equals 1 at 0

Best ResponseYou've already chosen the best response.0Pi and pi work, but they're certainly not the only answers. Positive and negative 1.231, 5.052, and 7.514 work as well.

Best ResponseYou've already chosen the best response.0tan² x 2 sec x = 2 sec² x  1 2 sec x = 2 sec²x  2 sec x  3 = 0 (sec x  3)(sec x + 1) = 0 sec x = 3, sec x = 1

Best ResponseYou've already chosen the best response.0oh I see 2secxsec^2x2 = 0

Best ResponseYou've already chosen the best response.0I factored. and you have them reversed in the equation you just wrote

Best ResponseYou've already chosen the best response.0ah right. so but secant never = 3 on the unit circle..

Best ResponseYou've already chosen the best response.0yes, pi is a solution. For sec x = 3, the solution is x = arcsec 3

Best ResponseYou've already chosen the best response.0ah k. So for me with my little scientific calculator how do I do arc sec 3

Best ResponseYou've already chosen the best response.0sec x = 3 cos x = 1/3 x = arccos (1/3)

Best ResponseYou've already chosen the best response.0that'll give you an angle in the 1st quadrant. Subtract it from 360 to get the angle in the 4th quadrant.

Best ResponseYou've already chosen the best response.0does it work to add two pi to that? or just subtracting it from 2pi?

Best ResponseYou've already chosen the best response.0the answers they give are kpi = we have this one! 0.72+2kpi = we don't have this. 5.56+2kpi = and we dont' have this either.

Best ResponseYou've already chosen the best response.0adding 2pi just gives the same angle you already found. Subtracting x from 2pi gives the angle in the 4th quad. Where did these answers come from?

Best ResponseYou've already chosen the best response.0aah I see the answer part of the book I'm doing the odd problems in my textbook which gives the answers in the back.

Best ResponseYou've already chosen the best response.0I'm getting 5.05 and 1.23

Babynini

Best ResponseYou've already chosen the best response.0Sorry, yeah. I was looking at 7 instead of 5. the answers are (2k+1)pi, 1.23+2kpi, 5.05+2kpi

anonymous

Best ResponseYou've already chosen the best response.0ok. you know how to get those?

Babynini

Best ResponseYou've already chosen the best response.0um 1.23, 5.05 came from theta = arcos(1/3) and pi came from sec(theta)=1

Babynini

Best ResponseYou've already chosen the best response.0and I understand the adding 2pi(k)

Babynini

Best ResponseYou've already chosen the best response.0I'm not sure why the pi one is written as (2k+1)pi ?

anonymous

Best ResponseYou've already chosen the best response.0That's the same as π+2πk. They factored the pi out

Best ResponseYou've already chosen the best response.0haha I told myself I would keep doing these until I get the answer entirely on my own..but going like this it seems that won't be anytime soon =.= K, this one makes sense now though :)

Best ResponseYou've already chosen the best response.0ok great. Maybe take a break if you don't have a deadline. These definitely take time to get used to

Best ResponseYou've already chosen the best response.0yeah give it a few years, you'll either never use it, or wonder how you lived without knowing it. There's no inbetween
