Name | Formula |
Sum of Arithmetic Series | Sn = n/2[2a + (n-1)d] |
Sum of Geometric Series | Sn = a(r^n - 1) |
How to find r = common ratio | r = tn+1 / tn |
Standard Form for Quadratic | y=ax^2+bx+c |
General geometric Sequence | tn = ar^n-1 |
Vertex Form | y=a(x-h)^2+k |
Simple Interest 1 | I = Prt |
Simple Interest 2 | A = P + I |
Compound Interest | A=p(1+i)^n |
domain & Range: y=2x^2 + 3x + 1 | completing the square factoring. divide mido by 2, square it + and -, kick - out and multiply anything, should look like parabola eqn |
Domain looks like... | D={x| -1 < x < 3} |
Range looks like... | R={y| -1 < y < 3} |
Reciprocal fxn: y=1/x starts in... | quadrant 2 and 3. 1, 0.5,0.5 |
reciprocal Fxn graphs need: | asymptotes, all labeled arrows, domain and range |
inverses | y=x, switching x and y coordinates |
determine eqn of LINEAR inverse: f(x)=5x-2 | replace f(x) with y, switch x and y now, isolate for opp of f(X) which is y |
determine eqn of reciprocal fxn inverse: y=1/x-2 + 3 | replace y with x, isolate for y |
quadratics has _ | (i) which = -1 for square roots |
