logistic_guy replied to the thread the equation (x + a)(x - a) = 16.👏👏 I loved how you cracked it Smith. You are absolutely from another planet. You can see things from a completely different angle! Are... -
logistic_guy reacted to Agent Smith's post in the thread the equation (x + a)(x - a) = 16 with
Like.
(1, 16), (2, 8), (4, 4) Also, x^2 - a^2 = 16 \implies x^2 = a^2 + 4^2 \implies 5^2 = 3^2 + 4^2 \implies x = 5, a = 3 -
logistic_guy replied to the thread line integral.One of the most beautiful topics after surface integrals is line integrals. We have to find the line integral: \int_C f(x,y) \ ds We...

Agent Smith replied to the thread 0.999... = 1.0.999... is to be asked to compute a limit and the limit is 1. I don't quite get the part where 1/infinity is a.s. 0 but not 0. In my...

It is a definition insofar as a limit is defined. The LHS makes only sense as 0.999\ldots=\displaystyle{\sum_{k=1}^\infty...

logistic_guy replied to the thread area between two curves.Let us find the intersection points. 3 - x = x^2 - 9 x^2 - 9 - 3 + x = 0 x^2 + x - 12 = 0 (x + 4)(x - 3) = 0 x = 3 Or x = -4 Then...

logistic_guy replied to the thread easy but hard differential equation.The homogeneous solution is: u(t) = c_1e^{-t}\cos 3t + c_2e^{-t}\sin 3t
