Given cos(2α)=49/81 and 0<2α<π/2
, find exact values of
the six trigonometric functions.
Note: You are not allowed to use decimals in your answer.
sin(α)
= .
cos(α)
= .
tan(α)
= .
csc(α)
= .
sec(α)
= .
cot(α)
= .
since lies between 0 to π/4 i.e in first quadrant .there fore all trigonometric ratios will be positiveplease do upvote ? if you found my solution helpful in anyway
