Homework Statement
1. A group of American physicists works on a project where planar lines are in the form
X=t⋅P+s⋅Q
where P , Q are two fixed different points and s,t are varying reals satisfying s+t=1 . They need to know formulae for the images of the line X=t⋅P+s⋅Q in the following...
2. A group of Japanese physicists works on a project where planar lines are in the form of solutions to equations
a⋅x+b⋅y+c=0
where a , b , and c are fixed reals satisfying a2+b2≠0 . They need to know formulae for the images of the line a⋅x+b⋅y+c=0 in the following cases:
1. Under the...
