You made a mistake when writing the piecewise function,In the first function the sign is flipped the wrong way, same with the last one. Doesn't this change the answer?

Given specific magnitudes of P1 = 539 N, P2 = 431 N, l1 = 3 m , l2 = 4 m, l3 = 4 m determine the vertical reaction at the left hand beam support. Give your answer, with the correct sign, rounded to th...

My guts say the answer is No.  Don't just tell me that my guts are right because the determinant of a plane reflection is -1 but the determinant of any line reflection, and so too any product of line...

I have been presented with a strange work of art which appears to be gibberish or some kind of cipher, but might contain actual mathematical equations. I don't know enough math to recognize what, if a...

Can someone give me an example of two functions whose domain is R^2 and codomain R^2, the first is discontinuous function at the point (1,2), and the second one has no limit at (1,2), and for both fun...

Let $L_1, L_2 \subseteq \mathbb{R}^n$  be full-rank Euclidean lattices with generating matrices $A, B$ respectively (representing Minkowski-reduced bases), and let $d(A,B)< \epsilon$, for some fixe...

Let $L_1, L_2 \subseteq \mathbb{R}^n$  be full-rank Euclidean lattices with generating matrices $A, B$ respectively, and let $d(A,B)< \epsilon$, for some fixed positive real $\epsilon$. Then do the...

Let $C$ be a vector subspace of $\mathbb{F}_q^n$, and define the Hamming distance as follows: If $v, w \in C$, then $d(v,w) =$ number of non-$0$ coordinates of $v-w$, and $d(v) = d(v,0)$. For a linear...

I am wondering if 0/0 is an impossibility vs Undefined. Given that 0 is a privation of quantity. I'm wondering if 0/0 is really just asking if "nothing" can go into "nothing". If this is what the equa...
