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#
