FC: A YEAR IN REVIEW | We're Cooking!!!!

1: THE EQUATION OF A CIRCLE The standard form of the equation of a circle with center (h,k) and radius r is (x-h)^2+(y-k)^2=r^2. How I remember to find the center and the radius? I just take h and k and make it the opposite of what it is in the equation...so say if (x-2)^2 then h would be 2. The radius, you just take the square root of whatever the radius is.

2: Slope Intercept Form y=mx+b m=-4 y-int.=(0,-7) ALL YOU DO IS PLUG IN!!!! -7=-4(0)+b -7=0+b b=-7 y=-4x-7

3: ROW EQUIVALENT OPERATIONS 1. Interchange any two rows. 2. Multiply each entry in a row by the same nonzero constant 3. Add a nonzero multiple of one row to another row.

4: THE REMAINDER THEOREM If a number c is substituted for x in the polynomial f(x), then the result f(c) is the remainder that would be obtained by dividing f(x) by x-c. That is, if f(x) = (x-c) *Q(x) + R, then f(c) =R.

5: DETERMINING VERTICAL ASYMPTOTES For a rational function f(x) = p(x)/q(x), where p(x) and q(x) are polynomials with no common factors other than constants, if a is a zero of the denominator, then the line x = a is a vertical asymptote for the graph of the function.

6: COMPLEX NUMBERS A complex number is a number of the form a + bi, where a and b are real numbers. The number a is said to be the real part of a + bi and the number b is said to be the imaginary part of a + bi.

7: THE QUADRATIC FORMULA SONG!!! Negative b, negative b. Plus or minus square root, plus or minus square root. B squared minus 4ac, b squared minus 4ac. Over 2a, over 2a!!!!!!

8: PROPERTIES OF MATRIX MULTIPLICATION For matrices A, B, and C, assuming that the indicated operations are possible: A(BC) = (AB)C. Associative property of multiplication A(B+C)=AB+AC Distributive property (B+C)A=BA+CA Distributive property

9: EASTER | happy | Spring Time | PARAMETRIC EQUATIONS If f and g are continuous functions of t on an interval I, then the set of ordered pairs (x,y) such that x=f(t) and y=g(t) is a plane curve. The equations x=f(t) and y=g(t)are parametric equations for the curve. The variable t is the parameter.
