6 gives largest output and 12.7 or -.4 gives the smallest
Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
Write tan in terms of sin and cos.

Recall that

Rewrite and expand the given limand as the product

Then using the known limit above, it follows that
