I don't understand a good portion of the non-algebraic math behind much of the physics in my first semester college class. I understand everything with algebra, and can solve all problems, but I don't understand the relationships with vector cross/dot products, calculus derivations, DE, etc...

I considered at first that the problem seemed like it could be...
I’m in an honors calc-based physics 1 course at my college and I can’t audibly understand my professor. I tried looking for tutorials online, but I have no idea if what I’m looking at is calc-based physics or alg-based physics, and I don’t want to learn the wrong methods. Is there a difference...
Homework Statement
The position of a particle as a function of time is given by x=Acosbt, where A and b are constants. The first question asks to roughly plot the position of the particle over the time interval (0,7) seconds.
The second asks what time the particle passes the origin, and what...
Is there any website that has a database of physics (or other course) powerpoint slide sets?
For example, I am teaching both an introductory physics class, and a separate calc-based physics class of what should be the same general material as the non-calc-based. For the former class I am using...
1. Problem
A boatman crosses a river of width ##D## from a point ##O##, looking to get to point ##A## on the opposite riverbank. Suppose that the flowrate is uniform with velocity of magnitude ##v_0##. The boat has a velocity ##\vec{v_1}## relative to the water, with constant magnitude, and it...
Homework Statement
A wave pulse on a string is given by D(x) = D[0][/SUB]/(x[2][/SUP]+a[2][/SUP]), where D0 is a constant with units of cm3 and a is a constant with units of meters.
a. If the wave moves along the string at a velocity of v in cm/s, what is the transverse velocity of particles...
Homework Statement
In a physics laboratory the value of g , the gravitational acceleration in the vicinity of Earth, has been measured accurately by projecting a ball up an evacuated tube and electronically timing the passage of the ball in its upward and downward flight through two light...
Homework Statement
Positive charge Q is distributed uniformly along the x-axis from x = 0 to x = a. Determine
a. The electric field produced by the charge distribution Q at points on the positive x-axis where x > a.
b. A point charge q is then placed at x = a + r. Determine force on q due to Q...
I know two kinds formulas to calculate extrinsic curvature. But I found they do not match.
One is from "Calculus: An Intuitive and Physical Approach"##K=\frac{d\phi}{ds}## where ##Δ\phi## is the change in direction and ##Δs## is the change in length. For parametric form curve ##(x(t),y(t))##...
The Complete Idiot's Guide to Calculus
INTRODUCTION
I've never really been very good at math and when I found out I had to take a Calculus class I started to panic. Once I gathered myself I went to the local bookstore to see if I could get a book to read so i could get a heads start. We are...
Homework Statement
So I have a problem where I have a series and two other parallel insulators bringing a system from a temperature of Tzero to Ttwo. However, the two aforementioned temperatures have a huge difference thus causing kappa to vary with temperature. I am trying to know how to...
Homework Statement
An object with mass m undergoes simple harmonic motion, following 2 perpendicular directions, described by the equations:
x=a cos (wt), a>0,
y=b cos (2wt), b>0
a) find the equation of the trajectory
b) find the speed at any given time (so having t as a variable)
c) the...
As required by the Green's identity, the integrated function has to be smooth and continuous in the integration region Ω.
How about if the function is just discontinuous at the boundary? Actually, this function is an electric field. So its tangential component is naturally continuous, but the...
Hi! I am writing a calculus-based Introduction to Electricity and Magnetism. It is an HTML-based book with animations, interactive demos, quizzes, and so forth. The first draft is almost complete (I still have to write chapters on integration, induction, and wave optics), but I wanted to...
Hello! I'm going to take calculus based physics and calculus 1 in the fall. At my school they're corequisites. But I'd like to do well in both of them.
It really worries me that I'm taking calculus based physics when I haven't ever taken any calculus before. Should I take cal based physics while...
Do you have to take algebra/trig based physics first in order to understand calculus based physics better? Or is algebra based physics even required for calculus based physics?
I was just curious on what was everyone's first Physics book, or what was their first encounter with Physics?
My first academic physics book that was not calculus based was my junior year of high school and was Conceptual Physics: The High School Physics Program by Paul G. Hewitt, and then...
