Show that R-1(a)R(a) = I, where I is the identity matrix and R(a) is the rotation matrix. This equation shows that the inverse coordinate transformation returns you to the original coordinate system.
Let C be the following matrix:
C=( 1 2 3 -2
0 1 1 -2
-1 3 2 -8
-1 -2 -3 2 )
Give a basis for the row space of Cin the format [1,2,3],[3,4,5],
for example.
Given a plant with the genotype C/cm;
Ac+/Ac+, where cm is an unstable
allele caused by a Ds insertion. This plant is crossed
with another plant with the genotype C/cm where
cm is an unstable allele caused by Ac
insertion.
What phenotypes would be produced (including their proportion)?
Assume that Ac and c are unlinked, that the chromosome-breakage
frequency is negligible, and that mutant c/C is Ac+.
Suppose that ac + bd = 0. Show that vectors [a, b] and [c, d]
are perpendicular. The number ac + bd is called the dot product of
the vectors [a, b] and [c, d].
Let A be a 2×2 symmetric matrix. Show that if det A > 0 and
trace(A) > 0 then A is positive definite. (trace of a matrix is
sum of all diagonal entires.)
Consider the following AC circuit. Let R = 1.0kΩ, C = 150µF and
L = 10.0 mH. The AC voltage source is of frequency 60 HZ and has a
maximum voltage Vmax of 100 V. Find a) the capacitive reactance, b)
inductive reactance, c) total impedance, d) RMS current, e) voltage
drop across the inductor, f) voltage drop across the capacitor, g)
phase angle, h) draw the phasor diagram for all voltage drops and
the resulting phasor, and i) is...

Let C be the intersection of all the Cn's. You must show C is
closed, measurable, has positive measure, and contains no interval,
i.e., if x is in C, every epsilon neighborhood of x contains points
not in C.Analysis
i should have note 0<alpha<1
Start with the interval [0,1] and remove the middle open
interval of length alpha/3 to form C1. Cn is then formed by
removing the middle open interval of length alpha/3^n from each
closed...
