# Line integrals in a vector field
After learning about line integrals in a scalar field, learn about line integrals work in vector fields.

# How do you graph y = abs(x + 4)?
Mar 10, 2018
graph{y=|x+4| [-10, 10, -5, 5]}
#### Explanation:
graph{y=|x+4| [-10, 10, -5, 5]}
Noting that there's an absolute value sign, your $x$value will never reach below zero, reflecting the part where $x$ is zero straight across, which would make it the absolute value. | {} |
Question
If A is the set of all xϵR such that x(log x)2−3 log x+1>1000, and A=(a,∞) then √10a will be ___. ( (Base of logx is 10).
Solution
A=(1000,∞) (log x)2−3 log x+1>logx 103=3 logx 10 If log10 x=t then we have t2−3t+1>3t or t3−3t2+t−3>0 or t(t2+1)−3(t2+1)>0 or (t2+1)(t−3)>0⇒t−3>0 as t2+1 is always + ive ∴t>3 or... | {} |

How do you evaluate tan(arccos(2/3))?
Jun 10, 2015
$\tan \left(\arccos \left(\frac{2}{3}\right)\right) = \frac{\sqrt{5}}{2}$.
Explanation:
$\alpha = \arccos \left(\frac{2}{3}\right)$.
$\alpha$ isn't a known value, but it's about 48,19°.
$\tan \left(\alpha\right) = \sin \frac{\alpha}{\cos} \alpha$

Can some one check my work, I'm not sure if I am understanding how internal energy heat and work are related.
Work is defined to be positive if the system does work on the environment.
Q=$\Delta U$ +W
I am showing if the process is positive, negative or 0.
