Question

cot3π/4= ?

Answer 1

0.78

Answer 2

cos3 = 1 0r 0.99 * 3.14 /4

Answer 3

find tan(3pi/4) then take the reciprocal of the answer

Answer 4

and given its a 2nd quadrant angle... it will be negative... and it will also be an exact value

so find

\[\cot(\frac{3\pi}{4}) = \frac{1}{\tan(\frac{3\pi}{4})} = - \frac{1}{\tan(\frac{\pi}{4})}\]
