|[SOLVED] Why is the output negative?||March 10, 2015, 9:59 am|
This code is supposed to calculate e to the power x. It works fine at lower numbers, but then at x = 3.6, the output starts to decrease as x goes up. What's wrong?
EDIT: The problem was that "factorial" function was an int, so at high values, it won't work.
|Minor in mathematics||February 25, 2015, 1:27 pm|
I'm majoring in computer science (first year), and I'm thinking of taking minor in math. The reason is because of its connection to computer science (since it's a sub-field of math), and I like it a lot. The question is, are these a good pair?
For CS degrees, math courses include Calculus I and II, Discrete Mathematics, Statistics, Linear Algebra and Numerical Methods. As for the mathematics minor, it includes Calculus III, Foundations of Mathematics, Normal Differential Equations, Mathematical Analysis I, Abstract Algebra I and other math courses in the choice of the student.
I feel getting a minor in math is a waste of time. It's because where I live, computer scientists and engineers usually end up in programming jobs, or maintaining computers. So it's very likely that I won't work in the "theoretical" part of computer science, and I "assume" that math is applied more on the theoretical part than programming (or software engineering).
Shall I forget it and pursue other minors, or am I being ignorant about how good it is to study such pair?
|Shall I switch majors?||December 19, 2014, 9:30 am|
I'm currently majoring in Computer Science, but it is possible to switch to Computer Systems Engineering. In general, CS should focus more on math, theories and software-related stuff than CSE, but after looking through my university's guide for BA degree, it seems that CS is a bit "contained" in CSE. For example, CSE students take several courses that are essential to get into software engineering (programming, data structure and management, and software engineering courses), with another courses related to Electrical Engineering and hardware stuff, but some share the same name of other CS courses (AI, Operating Systems, Algorithms). Plus CSE students can take some courses in CS as elective courses.
You have to be good in Physics and Mathematics to switch or to do well, which I am good at both. I just keep feeling that I'm wasting a chance to study engineering and become good at both software and hardware rather than only focusing on Computer Science. At the end of the day, either degrees will likely get me the same job, but an engineer is usually generally known as being smarter (because he is an "engineer", plus the requirements to get engineering are harder than the ones to get into CS).
Should I stop listening to people who keep telling me that I've took the wrong choice choosing CS over CSE even though I can make it through in the latter major?

I have a form in html, but I don't know to make it perfectly aligned. I tried putting it in a table with two columns, but I still have problems:

1- A car, initially going eastward, rounds a 90 degrees curve and ends up heading southward. If the speedometer reading remains constant, what's the direction of the car's average acceleration vector?
2- A plane with airspeed 370 km/h flies perpendicularly across the jet stream, its nose pointed into the jet stream at 32 degree from the perpendicular direction of its flight. Find the speed of the jet stream.
3- An object undergoes acceleration 2.3i + 3.6j m/s^2 for 10 s. At the end of this time, its velocity is 33i + 15j m/s. What was its velocity at the beginning of the 10 s interval? By how much did its speed change? By how much did its direction change? Show that the speed change is not given by the magnitude of the acceleration multiplied by the time. Why not?
4- A particle leaves the origin with initial velocity v0 = 11i + 14j m/s, undergoing constant acceleration a = -1.2i + 0.26j m/s^2. When does the particle cross the y-axis? What's its y-coordinate at the time? How fast is it moving, and in what direction?
5- A jet is diving vertically downward at 1200 km/h. If the pilot can withstand a maximum acceleration of 5g before losing consciousness, at what height must the plane start a quarter turn to pull out of the dive? Assume the speed remains constant.

|So much "free" time (1-2 hours) that I hate to sit lonely in public, so I went/hid in the library which is a very friendly environment for spending time yourself. This is gonna be boring if I'm going to do this everyday.|

Also how is doubling time calculated in general.

I quit Doom.
I quit mapping.
I now discuss everything but Doom on the forums.
Am I growing up?
