(1)
(a)  cos((5π)/4) =

(b)  tan((5π)/4) =

(c) sec((5π)/4) =



(2)  Find the domain of the function f(x) = x^(1/2)/(1 + 2cos(x))

 

 

 




(3)  In this problem, θ is a number between 0 and π/2 for which csc(θ) = 2^(1/2).


(a)  sin(θ) = 1/2^(1/2)
(b) tan(θ) =sin(θ)/cos(θ) = 1/2^(1/2)/1/2^(1/2) = 1
