Formula - Set of algebraic symbols representing a mathematical fact, rules, or principles
Derivation of Formula - refers to the rearrangement of symbols in a formula to arrive at a
new one
Right Triangle - a type of triangle that has one right angle
180 - the total interior angle of a right triangle is
2- how many acute angle does a right triangle have
hypotenuse - it is the longest side of a right triangle
altitude - height of the triangel
base - foundation of the triangle
adjacent side - it refers to the side near to the reference angle
opposite side - refers to the side that is the farthest from the reference angle
Pythagorean Theorem - in a right triangle, the square of the hypotenuse is equal to the
sum of the squares of the legs
pythagoras - who formulated the pythagorean theorem
, c2 = sq.rt of a2 + b2 - the pythagorean theorem
Trigonometry - branch of mathematics that studies the relationships between sides,
lengths, and angles of a triangle
sine, cosine, tangent - 3 trigonometric functions
sine - quotient of opposite and hypotenuse
cosine - quotient of adjacent and hypotenuse
tangent - quotient of opposite and adjacent
angle of elevation - looking up
angle of depression - looking down
number and units - components of a measurement
Time - what physical quantity is constant to both measurement systems
Physical Quantity - refers to measurable quantities
Fundamental Quantities - these are the quantities that deals with basic measurements and
cannot be expressed in other quantities
Derived Quantity - any quantity that is a combination of fundamental quantities
