Cheat Sheet
- Function Analysis Fundamentals -
Master domain, range, and end behavior for polynomials and rationals by following MIT OpenCourseWare techniques. For example, analyze f(x) = (x−2)/(x+3) by locating intercepts, vertical asymptotes, and sign changes using a sign chart. This strategic approach eases solving pre calc questions in your precalculus practice test.
- Quadratic Equations & Parabolas -
Revise the standard form ax^2+bx+c and vertex form a(x−h)^2+k, using completing the square to find the vertex (h,k) efficiently. Apply the discriminant, b^2−4ac, from University of Utah resources to quickly determine the number of real roots on the precalculus test. Remember, (−b/2a) gives the x-coordinate of the turning point - gold for scoring high on precalc questions.
- Trigonometric Identities & Angle Relationships -
Internalize key identities like sin^2θ+cos^2θ=1 and angle-sum formulas sin(α+β)=sinαcosβ+cosαsinβ from University of Colorado Boulder materials. Use the memorable phrase "Oscar Had A Heap Of Apples" (Opposite, Hypotenuse, Adjacent) for SOHCAHTOA in triangle problems. Applying these in precalculus practice problems will solidify your skills for any pre calc challenge.
- Exponential & Logarithmic Connections -
Understand that e^x and ln(x) are inverses, and use the change-of-base formula log_b(a)=ln(a)/ln(b) as shown by Cornell University handouts. Practice converting growth models like P(t)=P₀e^(kt) into logarithmic form to solve for k or t swiftly. Fluency with these transformations is crucial on your precalculus practice test and daily precalc questions.
- Sequences, Series & Summation Techniques -
Differentiate arithmetic sequences (a_n=a+(n−1)d, S_n=n/2(a+a_n)) from geometric ones (a_n=ar^(n−1), S_n=a(1−r^n)/(1−r)) using MIT OpenCourseWare notes. Familiarize yourself with sigma notation (∑) and practice expanding small sums to detect patterns. Mastering these formulas makes tackling precalculus practice problems and your upcoming precalculus test feel like a breeze.
