# Trigonometry/The Unit Circle
The Unit Circle is a circle with its center at the origin (0,0) and a radius of one unit.
Angles are always measured from the positive x-axis (also called the "right horizon"). Angles measured counterclockwise have positive values; angles measured clockwise have negative values.

Posted on
It is given that dy/dx = 1/(e^x + 1)
y = Int[ 1/(e^x + 1) dx]
=> Int[(e^x + 1 - e^x)/(e^x + 1) dx]
=> Int[(e^x +1)/(e^x+1) - e^x/(e^x + 1) dx]
=> Int[(e^x +1)/(e^x+1) dx] - Int[e^x/(e^x + 1) dx]... |
