Speakers : Bruce H Edward,PH.D

Bruce H.Edwards Ph.D. He is professor of Mathematics University of Florida, Gainsville.He graduated from Stanford University at 1968 and Matematics Dartmouth College at 1976. He would explain about all about calculus. He told some applications of precalculus.

Some Applications of precalculus by Mr.Bruce :

1.Radio Activity and carbon-dating2.Compound intereset and finance3.Parabolic mirrors and whispering

galleries4.trigonometri

Application of Precalculus

More Application 1.SAT scores2.Leaning Tower of Pisa3.GPS4.Chemistry,physics,engineering

FUNCTION Type of cuntion by Mr.Bruce: 1.linear 2.Polynominal 3.Exponential 4.Logarithmic 5.Trigonometric

He gives a simple example about that : Ex : F(x) = F(2) = =4 F(-2) = -2² = 4 F(0)=0 He told : Domaiun is values you are allowed to plug into a function, the for

domain from the example function is all numbers. He told : Range is the set of all the outputs , then for range from the

example function is all positive numbers.

ABSOLUTE VALUE FUNCTION : Ex : f(X) = |x|, x >= 0 -x < 0 F(3) = 3, F(0) = 0 F(-5) = 5

Domain is all xRange is the set all non-negative real numbersFrom that, we know ABSOLUTE VALUE always

positive values.

And Last, he explain about algebra trigonometric :That used to solve: 1.Linear equations 2.Squences 3.Series 4.Conic sections 5.Parametric equations 6.Polar coordinates 7.Probability
