In mathematics, the term derivative refers to the rate of change of a function with respect to a variable. Derivatives play an important role in solving problems in calculus and differential equations including finding local extrema, solving optimization problems, finding inflection points, and describi...
Graph created with Desmos.com. Nonlinear Function vs. Linear Function: Steps In order to figure out if your function is linear or nonlinear, you have several options. From easiest to hardest, they are: Study the equation. If it neatly fits the equation y = mx + b, then it’s linear....
internal resistance was to be determined using a “homemade” resistor of approximately ##\;4 \Omega## for the load. Measurements of open circuit voltage, terminal (load) voltage, and current were to be made with a single multimeter. One soon discovered that an ##\approx 4 \Omega## resi...
Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way, ...
The digital SAT's built-in Desmos calculator is a powerful tool for the test. You can use it to perform complex arithmetic, quickly complete multi-step calculations, and even graph systems of equations. However, not every question requires this tool.Learning to solve questions without the use ...
