cot θ= 0.767, find sec θ and csc θ

 

cot θ = x / y     so x = .767 and y = 1

 

We need to find r   =  sqrt (.767^2  + 1)  = about 1.2603

 

sec θ  = r / x =  1.2603 / .767  = about 1.643

 

And

 

csc  θ  = r / y =  1.2603 / 1 =   1.2603

 

Realize that the cotangent is also positive in the 3rd quadrant which would make the above values of sec and csc negative, if theta was in that quadrant

 

 

cool cool cool
