Alternate Method to find the Nature of Stationary Points The sign of the first derivative \frac{df}{dx} on either side of the stationary point is another way for classifying turning points. We have a maximum if the first derivative is positive on the left side of the turning point and neg...
Well, just like in single variable calculus, tolocate the relative extrema of a function of two variables, we must findcritical points! If \(f\left( {x,y} \right)\) is defined on an open region \(R\) containing \(\left( {{x_0},{y_0}} \right)\), then the point \(\left(...
That’s why, if you’re looking to take sharper photos, you should brush up on your handholding technique. Grip your camera in one hand and cup a second hand under the lens. Keep the camera close to your body, keep your elbows tight, and – when possible – support yourself with a ...
The scan-to-BIM workflow begins with a laser scanner that can be attached to an aerial drone, affixed to a stationary tripod, and moved from place to place, or the scanner can be clipped to a person as they move around a site. The laser scanner records points in space corresponding to...
The advantage of a paper template is that it's easily accessible, cheap and doesn't require a computer. The main downside is it's tricky to make revisions. Moving frames around is nigh-on impossible, as is any kind of collaboration or sign-off....
Another idea is to find something to rest your camera on. If you don’t have a tripod, try and find an alternative — anything that is stationary and not prone to shake like your hand does. Then, use your camera’s timer function to take the shot. If you’re taking pictures of peop...
How to use Your Light meter To find your light meter look through your view finder. It should be that little line graph at the bottom that looks a little like this: –2 . . . 1 . . . 0 . . .1 . . .2 + (there should be a little flashing vertical line or “ticker” underne...
Finding the number of a boundary using a surface plot. Another method to find a boundary number is to move to any node in the Model Builder tree that has a boundary selection and then hover with the mouse pointer over the boundary. The boundary number is dynamically displayed in the upper...

On a 1978 flight to Europe, Amar Bose, the founder of Bose Corporation, put on a pair of airline-supplied headphones, only to find that the roar of the jet engines prevented him from enjoying the audio.He started making calculations right there on the plane to see if it was possible to...
