sin(x) if cos(x) =3/5
What is 4/5?
This is the slope-intercept form of a linear function.
What is y=mx+b?
Chance of getting heads twice in a coin flip.
What is 1/4?
This statement is used to produce a y-value as x approaches a certain value.
What is a limit?
This operator undoes a derivative, giving the original function from the derivative.
What is an integral/antiderivative?
Formula for area of a triangle
1/2*base*height
This basic trigonometric function is a wave with its y-intercept at 0.
What is f(x)=sin(x)?
The average value of a sample/population.
What is mean?
This operator finds the instantaneous slope of a function at every single point.
What is a derivative?/What is differentiation?
The antiderivative of 3x2.
What is x3?
What function would best model radioactive decay?
What is an exponential function?
This law is used to find a missing angle or side of an oblique triangle (Hint: sin(a)/A = sin(b)/B = sin(c)/C)
What is the Law of Sines?
The number that comes up most often.
What is mode?
The derivative of .5x2.
What is x?
The second derivative of position.
What is acceleration?
Vertex of concave up parabola that goes through (1,4) and (-1,4).
What is (0,2)?
This model is used to find values of sine, cosine, or radians based on certain triangle proportions.
What is the unit circle?
The odds of rolling a 7 with two dice
What is 1/6?
This method is used for differentiating composite functions (Ex. d/dx*(2x+5)3).
What is the Chain Rule?
The third derivative of sin(x).
What is -cos(x)?
Area formula for trapezoid
What is 1/2* (bottom base+top base)*(height)?
This technique is used to prove if a statement or formula is true for every natural number.
What is proving by Mathematical Induction?
The chance of getting at least one heads in two coin flips.
What is 3/4?
The derivative of tan(x).
What is sec2x?
There is a silo in the shape of a cylinder. Grain is added to it at rate of 3m3/min. This is how fast the radius is changing.
