( 1 / tan x ) + tan x = 1 / ( sin x cos x )
We will start with the left side:
( 1 / tan x ) + tan x = ( 1 / sinx/cosx ) + ( sin x / cos x ) =
= ( cos x / sin x ) + ( sin x / cos x ) =
= ( cos² x + sin² x ) / ( sin x cos x ) =
= 1 / ( sin x cos x ) , which is same as the right side. The identity is proved.

Find mFDE, given that EF is a diameter of the circle
muminat
The measure of angle FDE must be 90 degree, if D is a point on the circle. If D is not a point on the circle, we are unable to determine the measure of angle FDE.

When you have angle with the vertex on a circle and the sides go through the ends of the diameter, the angle is always a right angle.
