# It is the question about THE DIAGRAM. It in B?

If we use trig to find $S \hat{Q} R$ first
$\cos \theta = \frac{\sqrt{2}}{2}$
$\theta = {\cos}^{-} 1 \left(\frac{\sqrt{2}}{2}\right)$
$S \hat{Q} R = 45$
PQR is a straight line so subtract $S \hat{Q} R$ from 180

# Proof of the preliminary test for infinite series
## Homework Statement
Preliminary test: If the terms of an infinite series do not tend to zero, the series diverges. In other words if ##\lim_{ n \to \infty}a_n \neq 0## then the series diverges. But if the limit is 0 we have to test further.
Suppose a series a ser... | {} |

# Recovering a dependent column vector from a matrix after row reducing that matrix
This is an old exam question I remember how to do, but not why it makes sense. Take a matrix $A$:
$A=\left(\begin{array}{rrrr} 1 & 6 & 2 & -4 \\ -3 & 2 & -2 & -8 \\ 4 & -1 & 3 & 9 \end{array}\right)$
Then row reduce it:

# Pseudo-dimensions of quantum Lie groups
In my hunt for spurious "alternatives" to the $E_7$ family I always encounter "fake" solutions. They turn out to be mostly $E_7$ family solutions disguised by $q\rightarrow{i*q}$. The effect is that the dimension (at $q=1$) comes out totally wrong. Generalizing a bit:
