APPLICATIONS AND EXAMPLES
BUSINESS
Calculate the future value of a $1000 invest-
ment compounded annually at a rate of 6% for
7 years.
FV = p (1+i )n
= 1000 (1+0.06) 7
= 1503.63
PHYSICS
If a ball is thrown upwars with a velocity of 75
feet per second, what is its velocity at the end
of 1.6 seconds
( g = 32.2 ft/sec2) ?
Velocity: V = Vo - gl
= 75 - ( 32.2 x 16)
= 23.48 ft/sec.
Height: S = Vol - 1/2 gl2
= (75 x1.6)– (1/2 x 32.2 x (1.6 )
2
)
= 78.784 ft.

Trigonometric Functions
In this right triangle,
A = 5.7 feet and a = 30 degrees.
Determine the value of C.
sin a = A/C
sin 30 degrees = 5.7/C
C = 5.7 / sin 30 degrees
C = 5.7 / 5
C = 11.4
