Question

Find the exact value of the expression. Do not use a calculator. If tan θ = 9, find the exact value of cot (pi/2 - θ)

Answer 1

A. 8
B. 10
C. 1/9
D. 9

Answer 2

don't be fooled, it is the cofunction identity
\[\cot(\frac{\pi}{2}-\theta)=\tan(\theta)\]

Answer 3

therefore if \(\tan(\theta)=9\) you know \(\cot(\frac{\pi}{2}-\theta)=9\) also

Answer 4

thank you

Answer 5

its d) 9

Answer 6

yes

Answer 7

too simple
