A gradient of G% is equivalent toarctan(G/100) degrees.But be aware:On calculators, arctan will be labelled tan-1 and may require another key (eg shift) to be used. In Excel the function is atan().Calculators may give the answer in radians rather than degrees (depending on the settings), and Excel will give the answer in radians. To convert from radians to degrees, multiply the answer by 180/pi.
Concentration Gradient
find the gradient
The answer depends on the gradient of WHAT!
what do you mean by gradient of a scalar field? what do you mean by gradient of a scalar field?
basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.
Danube river gradient
these tiles are gradient.
(-1.5,0) (1.5,0) what is the gradient?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
Gradient= Vertical gain / Horizontal distance Hope this helps ;P
