About Mrs. Howell
This is Mrs. Howell's first name.
What is Mary?
This is the slope-intercept form of a linear function.
What is y=mx+b?
This is the chance of a certain outcome.
What is probability?
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?
This is something that Mrs. Howell shares with us and encourages us to share it too
What is good news?
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, symbol x̄ (x-bar)
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.
∫3x2dx
What is x3?
These are the 3 subjects that Mrs. Howell teaches
What are pre-calculus, statistics, and calculus?
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?
This distribution has a roughly equal mean and median, and looks symmetrical.
What is a normal distribution?
The derivative of x2.
What is 2x?
This method is used to find the area under a curve by adding the areas of an infinite number of rectangles.
What are Riemann sums?
Mrs. Howell believes this is good for the soul.
What is calculus?
This model is used to find values of sine, cosine, or radians based on certain triangle proportions.
What is the unit circle?
This model has a natural limit (carrying capacity) and slows its rate of change at the point of inflection.
What is a logistic model?
This method is used for differentiating composite functions (Ex. d/dx*(2x+5)3).
What is the Chain Rule?
The definite integral of x2 from 0 to 4
∫04x2dx
What is 16/3?
This candy was used to demonstrate the Chi-Square Goodness of Fit Test
What are M&M's?
This technique is used to prove if a statement or formula is true for every natural number.
What is proving by Mathematical Induction?
This test is used to verify if assumptions about a proportion are true.
What is the Goodness of Fit Test?
The derivative of arctan(x).
What is 1/(1+x2)?
∫4x*sin(x2)dx
-2cos(x2)+C
