Question

Evaluate the following expressions. 
Note: The answer must be given as a fraction, NO DECIMALS. If the answer involves a square root it should be entered as sqrt . For instance, the square root of 2 should be entered as sqrt(2).

If cosθ=−2/9  and tanθ<0 , then 
sin(θ)=   
tan(θ)=   
cot(θ)=   
sec(θ)=  
csc(θ)=

anonymous · Answer

First make a triangle for the cos function. From there you can get the quadrant since you know tan is less than 0. Remember that Cos is adjacent over hyp. and tan is opposite over adj.
