what is worthy of noting in this picture?
Computer
Jun 22, 2017 00:44
spring shape
Computer
Jun 22, 2017 00:44
nvm sounds like it has something to do with sine
Computer
Jun 22, 2017 00:44
I don't know what sinusoidal means
Computer
Jun 22, 2017 00:43
that was very helpful
Computer
Jun 22, 2017 00:43
thank you
Computer

hm
Computer
Jun 22, 2017 00:43
true value for the total area?
Computer
Jun 22, 2017 00:41
as minimum
Computer
Jun 22, 2017 00:41
and 3pi/2
Computer
Jun 22, 2017 00:41
as my maximum area
Computer
Jun 22, 2017 00:41
oh pi/2*7
Computer
Jun 22, 2017 00:40
or is it pi/2*f(7)?
Computer
Jun 22, 2017 00:40
so pi/2*f(pi/4)= max area?
Computer
Jun 22, 2017 00:39
Unless you're saying those are my maximum and minimum areas?
Computer
Jun 22, 2017 00:39
so those are my bounds, I still have the integrand of 3+4sin(2x) and the given bounds of 0 to pi/2 to evaluate maximum and minimum value.
Computer
Jun 22, 2017 00:38
whether it is f(0) or f(pi/2) its still 3
Computer
Jun 22, 2017 00:37
3,7?
Computer
Jun 22, 2017 00:37
on the lower bound f(0)= 3
Computer
Jun 22, 2017 00:37
on the upper bound
Computer
Jun 22, 2017 00:37
so f(pi/4) = 7
Computer
Jun 22, 2017 00:36
pi/4 is a value of f(x)? no?
Computer
Jun 22, 2017 00:35
0,pi/4?
Computer
Jun 22, 2017 00:33
?
Computer
Jun 22, 2017 00:33
pi/2 is my min bound
Computer
Jun 22, 2017 00:33
pi/4 is my max?
Computer
Jun 22, 2017 00:33
So you're saying what exactly?
Computer
Jun 22, 2017 00:32
-16
Computer
Jun 22, 2017 00:31
2*2^(1/2)+3
Computer
Jun 22, 2017 00:30
7
Computer
Jun 22, 2017 00:30
f(pi/2) = 3
Computer
Jun 22, 2017 00:29
f(0)= 3
Computer
Jun 22, 2017 00:29
so f(0) and f(pi/20
Computer
Jun 22, 2017 00:29
s0 f
Computer
Jun 22, 2017 00:28
i have some integrand 3+4sin(2x) on the bounds 0 to pi/2
Computer
Jun 22, 2017 00:28
but I have now a min at x=pi/4...
Computer
Jun 22, 2017 00:27
makes sense
Computer
Jun 22, 2017 00:27
yes
Computer
Jun 22, 2017 00:26
oh minimum
Computer
Jun 22, 2017 00:26
so we have a maximum
Computer
Jun 22, 2017 00:25
4 sqrt(2)
Computer
Jun 22, 2017 00:24
pi/4
Computer
Jun 22, 2017 00:23
yeah, cos(pi/2)?
Computer
Jun 22, 2017 00:22
oh 0
Computer
Jun 22, 2017 00:21
?
Computer
Jun 22, 2017 00:21
pi/2+pi*n for all n in integers
Computer
Jun 22, 2017 00:20
no
