Find the values of
k
for which the system of equations
(3k 8)x 3y 3z 0, 3x (3k 8)y 3z 0, 3x 3y (3k 8)z 0...
l²+l²
2²+2²
x = 3y/y-8
make y the subject
4^-2 * 7^-2
\int _{-\infty }^{+\infty }\:\frac{1}{\left(1+x^2\right)^2}dx
F = {P ∈ ℝ₂[X] : P(1) = 0}
1. Montrer que F est un sous-espace vectoriel de ℝ₂[X] :
h(x)=(2x+4)/(-2x)
h^-1(x)=?
h(x)=(2x+1)/(x-4)
f(x)= (2x+4)/(-2x)⇒ $f^{-1}$(x) =?
