To find the gradient of a curve, you must draw an accurate sketch of the curve. At the point where you need to know the gradient, draw a tangent to the curve. A tangent is a straight line which touches the curve at one point only. You then find the gradient of this tangent. Example. Find the gradient of the curve y = x² at the point (3, 9). [Grade level: 6-8 | Topics: decimals, unit conversions, graphing a timeline, finding areas under curves using rectangles] Problem 36 The Space Station Orbit Decay and Space Weather Students will learn about the continued decay of the orbit of the International Space Station by studying a graph of the Station's altitude versus time. Spiral Curves Made Simple No. 6 Calculate the radial line and radius point for the main curve. Calculate the back deflection from the S.C. to the SPI is as follows: Delta(s) – Def = Back Def 2.0000 – 0.666666 = 1.333334(ddd) ~ 1-20-00(dms) Dec 28, 2020 · MS Excel Spreadsheets (XLS, XLSX) This section is dedicated to tools every electrical engineer can use in daily work. These spreadsheets developed by enthusiasts will make your job much more easier, alowing you to shorten the time used for endless calculations of power cables, voltage drop, power factor, circuit breakers, capacitors, cable size, power transformers etc. Nov 09, 2018 · This online grade curve calculator allows a teacher to enter a series of grades and rescale them onto a linear grade distribution. A linear grade distribution takes the lowest grade, sets it equal to your set minimum; and takes the highest grade and sets it to your set maxiumum. Any other grades are scaled between these two points. calculate k for kP= O. ECC Calculator. disclaimer: implementation is not rock solid industrial strength.
