To avoid round-off error when using trigonometric functions, angles in intermediate calculations should generally be taken to at least two places beyond the decimal point.
To avoid round-off error when using trigonometric functions, angles in intermediate calculations should generally be taken to at least two places beyond the decimal point.
Care should be taken not to round intermediate answers too soon during a solution. This will cause a loss of accuracy in the final answer. If the final answer is […]
A calculated answer should contain no more significant digits than the number of significant digits in the given data.
A symmetric matrix has off-diagonal terms.
Euler integration technique. Changes in the slope over the subinterval introduce error. A step size which is too small can result in increased error due to a very large number […]
For small angles sin(angle) = tan(angle) = (angle) and cos(angle) = 1 provided that the angles are expressed in radians.
If the hypotenuse is unity the arc length 1x(angle) and sin(angle) are very nearly the same.
Accuracy to three significant figures is considered satisfactory for most engineering calculations.
The number of significant figures in an answer should be no greater than the number of figures justified by the accuracy of the given data.
