Answer:

...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)  

arccos(0) is pi/2, plus or minus any multiple of pi.

Step-by-step explanation:

 

cotθ = cosθ  

cosθ/sinθ = cosθ  

sinθ = 1  

θ = π/2

pi also = to 3.14 etc.

Answer:

Step-by-step explanation:

[tex]cot \theta = cos \theta\\ \frac {cos \theta}{sin \theta} = cos \theta[/tex]

An easy solution is if [tex]cos \theta = 0[/tex], or [tex]\theta = \frac \pi 2[/tex], plus or minus any number of half circles.
