Review these terms and concepts related to algebra that may be tested on the Quantitative Reasoning section of the GRE test.
axis
If you think of the center of the dinosaur as the
axis, the tail was working to keep the creature balanced as its body weight shifted from left to right during a run.
convert
“It’s really, really difficult right now to just buy U.S. dollars and
convert rubles into dollars or any other currency in Russia.”
coordinate
But Hipparchus was the first to define the locations of stars using two
coordinates, and to map stars across the whole sky.
equation
For instance, the simple
equation 4x – 12 = 0 describes how an unknown number x is related to 4, 12, and 0.
equivalent
This summer, it was able to match premium animal egg prices in many markets for the first time, offering its mung bean protein eggs for $3.99 a bottle, the
equivalent of eight eggs.
exponent
Squaring a number doubles the
exponent, and for the base 2, adding one to the
exponent corresponds to doubling the number.
expression
We know that we must follow the order of operations to simplify
expressions with square roots.
factor
Remember that the bigger the number, the smaller the risk, and that for every unit increase in the safety index, the risk declines by a
factor of 10.
formula
Obesity is defined by a measure called body mass index, which is based on a
formula that divides one’s weight in kilograms by the square of one’s height in meters.
function
Likewise, the square root of the limit of a
function equals the limit of the square root of the
function; the same holds true for higher roots.
graph
The roller-coaster
graph lines tell the story of both unsustainable, sky-high prices and the huge losses that investors suffered if they bought during the end of the run-up and sold just a few days later.
horizontal
It considers not just the
horizontal distance between patches, but also factors such as the height and number of buildings that could hinder animals as they try to move from one habitat to another.
intersect
With Richardson’s curve and the simplest extrapolation for the future growth of the human population, the two curves do not
intersect until the thirtieth century or so, and Doomsday is deferred.
linear
Imaginary numbers never appeared in
linear equations, but they began to crop up in quadratic ones.
operation
It relied upon an illegal mathematical
operation, but it had one huge advantage.
origin
For example, a circle at the
origin can be represented by the set of all points where x² + y² – 1 = 0.
Zero: The Biography of a Dangerous Idea
plane
But unlike other species, krill most often changed direction based on neighbors in the vertical
plane, swimming toward peers ahead and below but away from those ahead and above.
quadratic
The
quadratic formula has been known for centuries; the ninth-century mathematician al-Khowarizmi knew how to solve almost every
quadratic equation, though he didn’t seem to consider negative numbers as roots.
root
The principal square
root is the nonnegative
root of the number.
vertical
Depending on whether it’s a toe pick jump or an edge jump, the movement patterns they do to get that
vertical velocity will differ. |
