Hint
Answer
Trigonometric function defined as the ratio between the opposite side and the hypotenuse
Cosine
Conic section that has an eccentricity equal to 1
Parabola
Part of the quadratic formula inside the radical sign that determines the number of distinct roots of a quadratic equation
Discriminant
A special kind of differential equation which has the form: dy/dx + yP(x) = Q(x)y^n
Bernoulli
A property of a square matrix A that is denoted by |A|
Determinant
A type of beam that has a fixed support at only 1 end
Cantilever
Condition that occurs when the sum of all forces and the sum of all moments acting on a body are equal to zero
Equilibrium
Ratio between the deformation of a body caused by subjecting it to stress and its original length
Poisson's ratio
Stress divided by strain (when the body obeys Hooke's Law)
Modulus of elasticity
Change in pitch that occurs when a sound source is moving with respect to the listener
Doppler effect
The frequency of a pendulum is only dependent on the acceleration due to gravity and this property of the pendulum
Length
Electric current multiplied by the voltage results in this quantity
Power
When circuit elements are arranged in this type of circuit, the current flowing through them is constant
Series
An integral transform that converts a function in time to a function of s which is equal to the integral of the product of the function in t and e^(-st), from zero to infinity
Laplace
The law of thermodynamics that states: if object A is in thermal equilibrium with object B, and object B is in thermal equilibrium with object c, then object A is in thermal equilibrium with object C.
Zeroth
The most efficient type of heat engine
Carnot
A thermodynamic quantity that represents the degree of disorder in a system
Entropy
A type of interest which is of the form F = P(1 +iN) where F is the future worth, P is the present worth, i is the interest, and N is the number of interest periods
Simple
