The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. tangent right triangle trigonometry the unit circle.
The focal length of a concave lens is negative because it is a virtual focal point rather than a real one. Therefore our measurement for f must have -f substituted. Additionally, the image is formed on the same side of the lens as the object, so Di is a negative number, making the measurement we want (-f + Di) as:
