Answer:
b. K,M,J,L
Step-by-step explanation:
From weakest to strongest values:
-0.78, -0.15, 0.35, 0., 67
Weakest to strongest data sets:
K, M, J, L
Cot²x/csc+1
=(csc²x-1)/(csc+1)
=((1/sin²x)-1)/((1/sinx)+1)
=((1-sin²x)/sin²x)/((1+sinx)/sinx)
=(1-sin²x)/(1+sinx)
=(1+sinx)(1-sinx)/sinx(1+sinx)
=(1-sinx)/sinx
