Simplify the expression sin a(csc a-sina)

a) 1-cos a
b) sin^a
c) 1
d) 1-sin a
e) cos^2 a

0 is its x and y coordinate

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
