Question

solve cos x + sin x tan x = 2
I have trouble with these problems

Answer 1

(cos ^2 x+sin^2 x)/cos x =0.5
1/cos x =2
cos x =.5
hence x is 60 degrees

Answer 2

How did you get (cos^2 x + sin^2 x)/ cos x =.5

Answer 3

convert the tan x into sin x/cos x then simplify!!!

Answer 4

did you get it??

Answer 5

mostly, how did you get .5 and where it says (cos^2x + sin^2x) how did you get cos to be cos^2

Answer 6

see
cos x+sinx*(sinx/cosx)=2
now on simplifying the fraction...
(cos^2 x+sin^2 x)/cos x=2
As cos^2 x+ Sin ^2 x=1
then 1/cosx =2
therefore
cos x=1/2
hence x=cos (inverse) 1/2
x= 60 degrees

k thank you
