Attached is the system that I created from the given information
This is the third question on our homework, so the writing on it is from the first two questions.
Homework Statement
A Koenig eyepiece with a focal length of 100mm is constructed in the following way:
The first lens is made of 755276 glass which is 10 mm thick on axis. The radius of curvature of its left hand surface is -225mm, the radius of curvature of it right hand surface is 83.6...
Homework Statement
What is the integral from negative infinity to positive infinity of the following functions?
a) f(z) = \frac{e^{-i5z}}{z^{2}+1}
b) f(z) = \frac{e^{-i5z}}{z^{2}-1}
c) f(z) = \frac{1}{π}\frac{a}{z^{2}+a^{2}}
d) f(z) = e^{\frac{-(z-ia)^{2}}{2}}
e) f(z) = \frac{sinz}{z}...
What do I end up doing with the 2r now?
All of my examples from class always end up looking like
r^{2}=(some coefficient)(a variable)
we never have a term with r remaining
Homework Statement
Curve C is given in Polar Coordinates by the equation r=2+3sinθ.
Consider the usual Cartesian plane and take O as the pole and the positive x-axis as the polar axis.
Find points on the curve C where the tangent lines are horizontal or vertical and sketch the curve C...
1,2,3 and 4 are the strokes of the cycle. Well the different points on the picture. and δ is supposed to be gamma, which is the adiabatic exponent.
I thought I could use
W=∫pdV = C_{v}(T_{1}-T_{2}
for the compression stroke...but I guess that is incorrect
Homework Statement
Derive a formula for the efficiency of the Diesel cycle, in terms of the compression ratio V1/V2
Homework Equations
e=\frac{W}{Q_{h}}
w= ∫pdV
The Attempt at a Solution
Now I know I should have used e=1-\frac{Q_{c}}{Q_{h}} to get it but he said it is...
Homework Statement
f(x)=\frac{4x}{(4+x^{2})^{2}}Homework Equations
\frac{1}{1-x} = \sum x^{n}
The Attempt at a Solution
How am I supposed to use that equation to solve the main problem. I have the solution but I don't understand how to do any of it. My professor is horrible, been on...
How about:
If I use the comparison test for
\frac{1}{ln(2n+3)} and compare with \frac{1}{n}
\frac{1}{n} is a divergent p series
using the comparison test, \frac{1}{ln(2n+3)} is also divergent?
