So you need help learning Algebra, Trig or Calculus! I guess the reason you're seeking help is not because you watch ?The Big Bang Theory? and have seen strange math equations that were written on their whiteboard, but rather, you are currently enrolled in a math course in your high school or college that appears confusing and ambiguous. I too struggled while taking my required math classes. Between my two college degrees, I had 7 semesters of Calculus / Linear Algebra / Differential Eq... [more]
I worked with Autocad 12 and Autocad 97 for several years while employed as a designer for industrial equipment. I'm familiar with paper/model space, layers, blocks, dimensioning and reference drawings. I periodically used isometric mode as necessary. Presently I have DraftSight (an Autocad clone) on my home computer.
I taught myself C after learning fortran, Basic/basica. I taught myself Borland C on my home computer in the early 90's. I'm a fan of structures and graphic modes. My senior project (at DeVry) involved programming an 8088 computer (in C) to drive a circuit board of my own design. Today, my expertise allows me to drive LCD displays and stepper motors under microcontroller control using C instructions.
I am well versed in digital logic commands such as "and", "or", "nand" and "nor" gates (and various combinations of the same). Typical chips supporting digital devices include 7400, 7402, etc. What I really liked was the programmable chips such as the 8255 - programmable interface adapter! I previously completed 2 successive courses in Digital Devices and currently use logical devices to decode digital addresses in computer type circuits.
I graduated from DeVry University in 1997 with an ASEET. I graduated with a 4.0 GPA. I took courses such as Digital Systems, Op-amps, Microprocessor, in addition to standard fare such as Electronics I and II and AC theory. I worked as an electronic technician, repairing circuit boards returned by the customers. The repaired boards were certified to NIST standards prior to returning to the customer.
