Hello!
I have a homework for tomorrow. The question is: What are the consequences of the Pythagorean theorem??
On Wikipedia, they mixed the consequences and the uses of the theorem in one paragraph:
5.1 Pythagorean triples
5.2 Incommensurable lengths
5.3 Complex numbers
5.4...
Hello everyone,
I was solving this problem:
Justify that ln6= ln2+ln3
So: exp(ln2+ln3)=exp(ln2)*exp(ln3)= 2*3= 6 = exp(ln6)
Till here, my work was okay.
What I didn't understand is : why should we say that the exponential function is strictly increasing over R before being able to simplify the...
Re: locus of a point in Space
why the support vector is the null vector?
if we take for example the two lines
(d): x=3t+2 (d'): x=t'+1
y=-t-1 t belongs to R and y=2t'-3 t' belongs to R
z= t+1...
Re: locus of a point in Space
Thanks a lot! yes I can see it :)
but why should I show that the vectors (1/2,-1,-1/2) and (-3/2,-4,-1/2) are independent in part 3?
And what if the two lines m and n are intersecting? what will be the locus of the midpoint of segment MB?
Hello everyone,
Here's an exercise I have to solve:
Given an orthonormal basis (O;i,j,k) and two lines m and n whose respective parametric equations are:
x = 2+t x = 4-3t'
y = 3-2t (t belongs to R) and y = 5-8t' (t' belongs to R)
z = 5-t...
