Question

How do you find the value of `cot 45`?

Answer 1

The value of `cot45` is 1.

You can get a right angled triangle with the other two angles of 45 degrees by drawing a diagonal in a square.
Now if you calculate the values of trigonimetrical functions of 45 deg you find that both `tan45` and `cot45` is 1. Tangent and cotangent of an angle is the quotient of 2 catheti, which are equal, so finally `tan45=cot45=1`
