Hey,
Im trying to figure out which engineering I should do. I am doing a dual degree in physics and engineering. I am pretty much done with physics. I was going to do electrical engineering, but i don't think its right for me. I am thinking of doing civil engineering, but then i saw a degree in...
Homework Statement
This is from a physics problem, but says to evaluate the other three terms in the equation.
Going to just show the first one.
Homework Equations
(\theta 1/sin\theta d/d\phi)(\phi d/d\theta)
The Attempt at a Solution
in the book they show the solution, but no...

Homework Statement
This is a physics problem but don't understand the math really
f(x)=a(eix+ie-x2
Homework Equations
∫f*f =1
The Attempt at a Solution
I thought it would be f2=a(eix+ie-x2)*a(eix+ie-x2)
but they have it as a*(e-ix-ie-x2)a(eix+ie-x2)
Dont really know what the...
Homework Statement
show that y=ex-vt)7/8
Homework Equations
d2y/dt2= d2y/dx2
The Attempt at a Solution
i don't understand how they solve this. in the book they have dy/dt=ezdz/dt=-7/8vez(x-vt)-1/8
I thought it would be -7/8veex-vt)7/8 not sure what they did any.
thanks
