of your
130. BV:
B
O
B
131. Which is this, this is
b
.
132. the left of

141. Can we get every righthand side
b
?
142. sorry, Mrs.
B
, I'm covering your face up,
143. rotation matrices, that was the homework part
B
144. which would be axi plus
b
. I will write that as xia plus
b
145. when would I not be able to produce some
b
off here?
146. Au=
b
.
147. So if I give you this
b
, can you get x?
148. Invertible or not for
B
?
149. It's u equals A inverse
b
, right?
150. Buh
B

B
Boris?
151. equals A inverse
B
. So we have to multiply,
152. would be righthand sides
b
that I couldn't get.
153. has this, what I described here, didn't look at
b
.
154. If the user inputs a number for
B
such that
155.
b
is in the plane, but most righthand sides
156. If I have to compute A inverse and multiply by
b
,
157. if I give you
b
and ask for x?
158.
B
man? Oh you're there
159. "best fit" line of a form y equals ax
b
160. y over
b
squared equals one. That's the curve,
161. Every
b
means all the bs in three dimensional space.
162. the correct righthand side
b
.
163. over partial a= 0, partial d over partial
b
= 0.
164. There
B
double O T Y
165. Cloak and dagger stealth missions, assassinations,
B
&E (that's Breaking and Entering)
166.
B
. How do we solve that?
167. coefficients of a and
b
. If you have good eyes,
168. but different shading with respect to
b
instead of with
169. inverse times
B
. And the other case is when the
170. N times
b
equals sum of yi. Now, this quantities look
171. than or equal to
b
is this inequality.
172. showed that we could get every
b
.
173. X equals A inverse
B
. That's how I solved my system
174.
B
for both ends are going to be free.
175. So, in fact,
B
cross A and A cross
B
are
176. So, now, BX means we apply the transformation
B
to X.
177. 0,3, 0,2. So, in A times
B
,
178. A,
B
, and C. They will all get the job done.
179.
b
, or ability a to ability
b
, and make
180. When I look at that I see a matrix multiplying
b
.
181. Au=
b
.
