The Heaviside function (t){\displaystyle \Theta (t)} is the function that equals 0{\displaystyle 0} for negative t{\displaystyle t} and 1{\displaystyle 1} for positive t.{\displaystyle t.} As with the delta function, (t){\displaystyle \Theta (t)} does not have a Fourier transform in the usual sense because (t){\displaystyle \Theta (t)} is not absolutely integrable. Ignoring this warning, we can write out its Fourier transform by naively doing the integral. F{(t)}=0eitdt=eiti|0=1i{\displaystyle {\mathcal {F}}\{\Theta (t)\}=\int _{0}^{\infty }e^{-i\omega t}\mathrm {d} t={
rac {e^{-i\omega t}}{-i\omega }}{\Bigg |}_{0}^{\infty }={
rac {1}{i\omega }}} In order to make sense of this answer, we appeal to convolutions. The derivative of a convolution of two functions is given below. Note that this is not the product rule of ordinary derivatives. ddt(f(t)g(t))=fg=fg{\displaystyle {
rac {\mathrm {d} }{\mathrm {d} t}}(f(t)*g(t))=f'*g=f*g'} Then, we see that the convolution of the derivative of an absolutely integrable function f(t){\displaystyle f(t)} with (t){\displaystyle \Theta (t)} can be written in the following manner. This also implies the important relation (t)=(t).{\displaystyle \Theta '(t)=\delta (t).} f(t)(t)=f(y)(ty)dy=tf(y)dy=f(t){\displaystyle {egin{aligned}f'(t)*\Theta (t)&=\int _{-\infty }^{\infty }f'(y)\Theta (t-y)\mathrm {d} y\&=\int _{-\infty }^{t}f'(y)\mathrm {d} y=f(t)\end{aligned}}} F{f(t)(t)}=f^()=f^()^()=if^()^(){\displaystyle {\mathcal {F}}\{f'(t)*\Theta (t)\}={\hat {f}}(\omega )={\hat {f}}'(\omega ){\hat {\Theta }}(\omega )=i\omega {\hat {f}}(\omega ){\hat {\Theta }}(\omega )} In this sense, we may then conclude that F{(t)}=1i.{\displaystyle {\mathcal {F}}\{\Theta (t)\}={
rac {1}{i\omega }}.}

Summary: Evaluate the Fourier transform of the Heaviside step function.

Return to the position with your arms straight up in the air and your palms facing in towards each other. Keep your arms close to your ears and look straight ahead.' Make sure that you also stay in the same kneeling or standing runner's stretch position that you were in for the side stretch. Bend your knee to bring your hips forward and as you do this, turn your upper body to the right. Only turn as far as you need to feel the stretch in your hips. Depending on how tight your hip flexors are, this may only be a slight motion. Keep your arms raised in the air as you stretch and rotate. After you finish rotating and stretching to the right, repeat the movement, but rotate to the left instead. This will use a different range of motion, so you should notice that the stretch feels a little different. For example, in the first rotation, you might have felt the stretch in your outer thigh, and for this part of the rotation stretch, you may feel it mostly in your inner thigh. After you finish the last stretch in the 3D stretch sequence, take your right foot down from the chair and step up with your left foot instead. Then, go back to the first step again and repeat the entire sequence to do all of the same stretches on this side. If you were kneeling for the stretches, bring your right foot back and kneel on both knees. Then, move your left foot in front of you so you are kneeling on your right knee.

Summary: Raise both arms over your head. Lean forward and rotate your body to the right 3 times. Rotate to the left as you lean forward 3 times. Switch legs and repeat the entire 3D stretch sequence.

Choose a large decorative tray that's wide enough to hold your necklaces length-wise. Lay them out in a row in the tray, organizing by color or style as you go. The tray doesn't need to be made for jewelry. Try using a vintage serving tray, for instance. No matter where you buy jewelry, you often end up with small cardboard boxes. Use paperclips to attach them together. Set 2 bottoms side-by-side, and put the paperclip over the joined edges. Lay the boxes out in shallow drawer or tray. Place a necklace in each jewelry box. It's fine to let costume jewelry be out in the open, but you should protect more expensive jewelry from dust and damage. Place each necklace in its own jewelry box, and put the boxes away for safe keeping. You can also use jewelry boxes that have individual spaces for necklaces. Many of these are decorative and will look lovely sitting on a dresser or vanity.
Summary: Pick a decorative tray for an easy way to lay out necklaces. Organize necklaces in the cardboard boxes the jewelry came in. Hide more expensive pieces in individual jewelry boxes.
