As we learned in the lecture, computer software uses decimal degrees (DD), as they are much easier to handle in complex algorithms for various mapping applications.  Your task is to convert Lat-Long from DMS to DD and vice versa.  Remember: when using DD, the cardinal direction are replaced by positive and negative numbers .  The "+" sign is omitted (it is implied) and only the minus sign "--" is mandatory . (See lecture)   Washington Monument in DC has the following coordinates, in DMS:  LAT: 38 deg 53 min 22 sec North ; LONG: 77 deg 02 min 19 sec West.  Use an online converter (such as https://www.latlong.net/degrees-minutes-seconds-to-decimal-degreesLinks to an external site.) and find the coordinates in decimal degrees.  Choose the correct coordinates in DD for the Washington Monument: 38.88944444 , 77.03861111 38.88944444 , --77.03861111 --38.88944444 , 77.03861111 --38.88944444 , --77.03861111

I need help simplifying the following problem, see attached.  This is the problem written out in text: F = (a !b c + !a b c) + (a b !c + !(bc) + !c)   This problem is connected to logical circuts and I need to uderstand the steps to simplifying it. The second attached image is an example of a completed, simplified problem.

Computer Science Let C be a black circular disk in front of a white background. The circular disk is parallel to the image plane. This disk is projected on the image plane through a pinhole. What is the shape of the disk’s projection on the image plane? [Hint: A circular disk parallel to the image plane is described algebraically as all 3D points [X,Y,Z]T with (X-X0) 2 +(Y-Y0) 2 =R2 , Z=Z0, where [X0,Y0,Z0] T is the center of the disk and R is its radius.]
