AI Thread Summary
To find the parametric equations of a line through point A(-3,2,5) that is perpendicular to both given lines, one must first determine the direction vectors of line 1 and line 2. The direction vector for line 1 can be extracted from its parametric form, while line 2's direction vector is derived from its equation. The next step involves calculating the cross product of these two direction vectors, which yields a normal vector that defines the perpendicular line. Once the normal vector is established, the parametric equations can be formulated using point A and the normal vector. This approach effectively solves the problem of finding the required line.

Homework Statement



find the parametric equations of the line through A(-3,2,5) and is perpendicular to both line 1 and line 1 where

line 1: (x-4)/3=y-2=(z-3)/-2
line 2: (x,y,z)=(-1,1,5)+k(-1-2,3)


2. The attempt at a solution

i think i need to find the normal for the line 1 and line 2.. but I'm not sure.. also i have a unit test on this tomorrow.. so any help would be great

You need to find tangent vectors to both line1 and line2. Can you start by doing that? Are you, by any chance, in the same test as passenger48?
 
oh i finally figured it out.. i just need to do the cross product of the two dirction vectors of the two line..
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Greatest possible value of a constant in polynomial'

Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
