200What is all real numbers?
Domain of exponential functions

200What is cosecant (csc) ?
the trig function that is the reciprocal of sine

200What is 1 ?
the missing number in
sin^2 A + cos^2 A = _??_

300What is the slopes are opposite reciprocals ?
The way you can tell two lines are perpendicular by their equations

300What is f(x) = 1/2(x+9)?
Since g(f(x)) = x,
g(f(x)) = 2(f(x))  9 = x
and therefore
2(f(x)) = x+9
f(x) = (x+9)/2
if g(x) = 2x  9, find a function f such that g(f(x))= x

300What is the domain of f(x) is equal to the range of the inverse of f(x) and the range of f(x) is equal to the domain of the inverse of f(x)?
The graph of the inverse of f(x) is related to the graph of f(x) ....

300what is 2π/3?

300What is 2 ?
the value of tan x when cot x = 1/2

400What is x = 2 ?
the equation of a vertical line passing through (2,5)

400What is sqrt(3)/2?
Cos(π/6) = ?

400What is y = x ?
The graph of inverse functions is the reflection of the original graph over this imaginary line
(hint: give an equation)

400What is odd?
The symmetry of sine functions is ......

400What is a halfangle identity ?
If you need to find the exact value of the sine of 15 degrees, knowing the value of the sine of 30 degrees, the type of identity you need

500What is 3/4 ?
