Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
Okay so, your answer should be 10. I wrote out each step but my handwriting is bad. let me know if I need to redo it for you!
For this case we have the following equation:

If we add 1 to both sides of the equation we have:

Dividing between 2 on both sides of the equation we have:

The graph of the solution is shown in the attached figure.
