How does the 3D coordinate system work? In three-dimensional space we can label where any object is using the?x-y-z?coordinate system In the 3D cartesian system, the?x-?and?y-?axes usually represen...
What is an arc? An arc is a part of the?circumference?of a circle It is easiest to think of it as the crust of a single slice of pizza The length of an arc depends of the size of the angle at the c...
What are radians? Radians are an alternative to degrees for measuring angles 1 radian is the angle in a?sector?of radius 1 and arc length 1 A circle with radius 1 is called a?unit circle Radians ar...
What are cartesian coordinates? Cartesian?coordinates are basically the?x-y?coordinate system They allow us to label where things are in a two-dimensional plane In the 2D cartesian system, the hori...
What effects do reciprocal transformations have on the graphs? The?x-coordinates stay the same The?y-coordinates change Their values become their?reciprocals If?y?= 0 then a vertical asymptote goes...
How do I find the modulus of a function? How do I solve modulus equations graphically? To solve |f(x)| =?g(x) graphically Draw?y?= |f(x)| and?y?=?g(x) into your GDC Find the?x-coordinates of the?po...
How do I sketch the graph of the modulus of a function:?y?= |f(x)|? STEP 1: Keep the parts of the graph of?y?=?f(x) that are?on or?above the?x-axis STEP 2: Any parts of the?graph below the x-axis?g...
What is the modulus function? At the vertex The function is?continuous The function is?not differentiable 转载自savemyexams
How do I solve polynomial inequalities? STEP 1:?Rearrange?the inequality?so that?one of the sides is equal to zero For example:?P(x) ≤ 0 STEP 2: Find the?roots?of the polynomial You can do this by ...
