sec A can be 2
 9 months ago

kaylala Group TitleBest ResponseYou've already chosen the best response.1
I dont see any negative 2 in the graph list Sec A =2

sec A = 2 secA = 1/cos A cos A = 1/2 when ?
 9 months ago

kaylala Group TitleBest ResponseYou've already chosen the best response.1
I dont see any cos A =1/2 There is only cos A=1/2

Oh i see now So will the answer for secA=2 or cosA=1/2 be: A={120,210}
 9 months ago

kaylala Group TitleBest ResponseYou've already chosen the best response.1
Is that it already? How about sec=1/2? Does it really have no solution? @hartnn
 9 months ago

hartnn Group TitleBest ResponseYou've already chosen the best response.3
yes. in the range 0 to 360. range of sec function does not include values between 1 and 1 so, sec A = 1/2 will have no solution, (in the same way cos A = 2 have no solution)
