Study Notes
Point Slope Form
- Represents the equation of a line using a known point (x1, y1) and slope m: ( y - y_1 = m(x - x_1) )
Trigonometric Ratios
- Sine (sin): Ratio of the length of the opposite side to the hypotenuse in a right triangle: ( \text{sin} = \frac{\text{opposite}}{\text{hypotenuse}} )
- Cosine (cos): Ratio of the length of the adjacent side to the hypotenuse: ( \text{cos} = \frac{\text{adjacent}}{\text{hypotenuse}} )
- Tangent (tan): Ratio of sine to cosine: ( \text{tan} = \frac{\text{opposite}}{\text{adjacent}} )
Difference of Cubes Formula
- Can be factored as: ( a^3 - b^3 = (a - b)(a^2 + ab + b^2) )
Distance and Midpoint Formulas
- Point Distance Formula: Calculates distance between two points ((x_1, y_1)) and ((x_2, y_2)): ( \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} )
- Midpoint Formula: Finds the midpoint of a segment connecting two points: ( \left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right) )
Area Formulas
- Area of Square: ( A = s^2 )
- Area of Rectangle: ( A = lw )

- Area of Circle: ( A = \pi r^2 )
- Area of Trapezoid: ( A = \frac{1}{2}(b_1 + b_2)h )
- Area of Equilateral Triangle: ( \frac{s^2 \sqrt{3}}{4} )

Exponential Functions
- Exponential Growth Formula: ( y = a(1 + r)^t )
- Exponential Decay Formula: ( y = a(1 - r)^t )
Trigonometric Identities
- Pythagorean Identities:
- ( \sin^2 x + \cos^2 x = 1 )
- ( \tan^2 x + 1 = \sec^2 x )
- ( 1 + \cot^2 x = \csc^2 x )
- Double Angle Formulas:
- ( \sin(2x) = 2 \sin x \cos x )
- ( \cos(2x) = \cos^2 x - \sin^2 x )
- ( \tan(2x) = \frac{2 \tan x}{1 - \tan^2 x} )
Geometric Angle Formulas
- Inscribed Angle: Measures half of the arc it intercepts.
- Angle Formed by a Tangent and a Chord: Equal to half the measure of the intercepted arc.
- Angle Formed by Intersection of Two Chords: Average of measures of the arcs intercepted.
- Angle Outside the Circle: Difference between larger and smaller arcs, divided by 2.
Slope Relationships
- Parallel lines have equal slopes.
- Perpendicular lines have slopes that are opposite reciprocals, e.g., if one slope is ( 5 ), the other is ( -\frac{1}{5} ).
Job and Mixture Formulas
- Work Rate Formula: ( \text{Job} = \text{Work Rate} \times \text{Time} )
- Mixture Formula: ( (\text{percentage of solution}) \times (\text{volume of solution}) = \text{amount of liquid} )
