Trig homework help please?

Question

my calculator is weird, and im not sure if its giving me the right answer. what is cot 68 degrees 40 minutes?

Answer 1

68 degrees 40 minutes is the same as 68 + 40/60 degrees (and make sure you're in degrees mode)

since most calculators don't have a cot button, remember that cot = 1/tan

so cot 68 degrees 40 minutes = 1 / tan (68 + 40/60) = .3906

you could also calculate [cos (68 + 40/60)] / [sin(68 + 40/60)] = .3906

remember that there are 60 minutes / degree, and 60 seconds / minute

sec = 1 / cos

csc = 1 / sin

Answer 2

cos(68 40')

----------------

sin(68 40')

-2.078792876

Answer 3

40/60 = 2/3 = 0.666666

cot (68.66) = ?

Don't forget to set your calculator in degrees(if u want your angle to be in degrees)

Answer 4

cot 68deg 40min = 0.391

Answer 5

40 minutes? (not too sure what you mean by that)

Remember, cot 68 is the same as (cos 68) / (sin 68)

cot 68 ≈ 0.3746 / 0.9272

cot 68 ≈ 0.40401

Also, remember to set your calculator to degrees (if you want the answer to be in degrees)
