Answer 1

rate of change from b to a
\(\Large = \dfrac{f(b)-f(a)}{b-a}\)

Answer 2

from a to b ** (but it doesn't matter)

Answer 3

so
rate of change from 0 to pi/2
\(\Large = \dfrac{f(\pi/2 )-f(0)}{\pi/2 - 0} =...\)

Answer 4

can you fins f(pi/2)
?
is is value of curve when x=pi/2

Answer 5

*find

Answer 6

I have no idea how to solve that ._. except f(1.57) >< math is my worst subject
