My name is David H. I have degrees in applied mathematics from MIT (Master of Science) and Worcester Polytechnic Institute (Bachelor of Science) with much course work in statistics. I have worked for many years in scientific data analysis and modeling. I have experience as a teaching assistant, tutor, paper/homework grader, and exam proctor.
My strengths are mathematics and science, including algebra, geometry, trigonometry, calculus, probability, statistics, meteorology, astronomy and general science.
In high school, a lot of the kids who signed my yearbook thanked me for all the help I gave them with their math and science courses! In college, I was the dorm floor math guru. Now, let me help YOU!!
I can also provide lessons and coaching for those getting into digital photography for the first time. I did events which introduced people to digital photography with the MIT Club of Boston, an MIT alumni club.
Additionally, I can provide lessons and assistance with HTML for those who are working or considering working on building their first website. I also was a past Webmaster of the MIT Club of Boston, an alumni organization, and have won an award for outstanding work in 2000. I also have built and ran my church's first website and currently serve on their Web Team.
I took Algebra 1 in the 8th grade and have earned all A's, mastering simple equation solving, polynomial manipulation and factoring and solving word problems. I also had my first exposure to flow charting which was a computer programming tool in the 1970s.
I tutored a student with Algebra 1 from 1983 to early 1984 and another student through WyzAnt late spring of 2014.
I took Algebra 2 in the summer between the 9th and 10th grades and have earned all A+s. This included more complex equation solving, polynomial manipulation and factoring, solving word problems, logarithms, analytic geometry, and complex numbers. I won numerous awards in high school for outstanding scores in mathematics competitions.
I have an interest in astronomy going back to when I was in the 4th grade where I looked at
the final chapter in the general science text book which happened to be on astronomy and it
caught my interest. I have done several astronomy-related projects during my high school and college years. I also have been an amateur astronomer for the past 44 years. I own two telescopes and have related web pages on my website and a blog.
I have recently tutored a college student on Astronomy. I received a five-star rating from
the student on WyzAnt.
I took Calculus courses in the 11th and 12th grades and Freshman year in college and have earned all A's and A+'s. This includes limits, derivatives, integration, multivariate and vector calculus. I was the math guru on my dorm floor in college. I also graded calculus papers in college.
I took a course in Ordinary Differential Equations during my Freshman year in college. I also took courses in Boundary Value Problems and an Applied Mathematics course that used Differential Equations during my Sophomore year. I took a course on Numerical Solutions of Differential Equations during my Senior year. I earned A's in all of these subjects. I graded papers in college and was a Teaching Assistant in graduate school for several mathematics courses.
I took Geometry in the 9th grade and earned all As. This included proofs, similar triangles, measurement (areas, volumes) and solid geometry. I won numerous awards in high school for outstanding scores in mathematics competitions.
I built and maintained my first two websites - my personal site and one for my church starting in 1997 and 1998 by using the web site building tools in Netscape. I was also Webmaster of the MIT Club of Boston, an alumni club, from 1999 to 2004 when I taught myself HTML and Dreamweaver. I have also taught myself image editing using tools such as Paint Shop Pro and Photoshop. I won an award from the MIT Club of Boston in 2000 for outstanding work on their website.
I have very recently tutored a student in HTML and received a five-star rating from WyzAnt.
I took two Linear Algebra courses in college and have earned the equivalent of A's in both courses. The first course was titled 'Matrices and Linear Algebra' and I took it during my sophomore year. The other course was titled 'Intermediate Linear Algebra' and I took it during my junior year. The courses covered topics such as matrix algebra, using matrices to solve systems of linear equations, determinants, vectors, vector spaces, linear transformations and eigenvalues. I have used some of these concepts to run the Matlab scripting language at my most recent job.
I bought my first digital camera, a Nikon Coolpix 950, in 1999. I have since bought and used several Nikon and Canon and one Fujifilm digital cameras. I am the official photographer at my church. I also photographed events while I was Webmaster of the MIT Club of Boston, an alumni club, from 1999 to 2004. I use Adobe Photoshop and Corel Paint Shop Pro for my photo editing.
I also led a few digital photography-related events held by the MIT Club of Boston in 2003 and 2004 including a how-to event.
I took Analysis in the 10th grade and have earned all A+s. The course included trigonometry, complex numbers, symbolic logic, more complex equation solving, more advanced polynomial manipulation, solving word problems and logarithms. I won numerous awards in high school for outstanding scores in mathematics competitions.
I took the SAT in high school where I scored 780 in the SAT Mathematics Examination. I also achieved a perfect 800 in the SAT Math Level 2 Achievement test during my senior year in high school. I have also tutored a student in SAT Math through WyzAnt recently.
I took Probability and Statistics courses in college and graduate school and have earned the equivalent of all A's and B's. This included sampling, estimation, regression, correlation and hypothesis testing. I was also a teaching assistant in graduate school. I have generated and used statistical plots such as box plots and scatter plots at my most recent job for analyzing weather sensor data.
I learned trigonometry when I took Analysis in the 10th grade and earned all A+s. This includes solving triangles (Law of Sines, Law of Cosines), identities and analytic geometry-related topics. I won numerous awards in high school for outstanding scores in mathematics competitions.
I tutored a student in HTML in 2013. He was pleased with my work. I have degrees in applied mathematics from MIT (Master of Science) and Worcester Polytechnic Institute (Bachelor of Science) with much course work in statistics.
Easy to work with — David attempted to fill my need remotely, but eventually we had to meet face to face. David successfully launched my applet from my html file and did it easily. In so doing David upgraded my browsers to accept Java applications. I was very happy to see my application appear on my web page. David is very easy to work with. ...
