Find the absolute maximum and absolute minimum values on f on the given interval.
1. f(t) = t + cot (t/2) , [0,8]
2. little 3 on top of the square root of t (8 - t) , [0,8]
I am very lost because these two problems are killing me. Can anyone help me with these

I know there are continuous functions that are not differentiable, and
am wondering a few of things.
1.  Is there a common/popular  example that is most often referenced?
If so, what is it called?

Find   f(x)=int(1/1+(sint)^2) , t=a , t=x)

assuming the condition
r^2(a+b)-2r(gp+fq)+c(p^2+q^2)=0 is satisified
prove that the locus of the perpendicular from origin to the line
px+qy+r=0 is

Find   f(x)=int(1/1+(sint)^2) , t=a , t=x)

I have some question i hope anyone could clarify for me.
I am asked whether a relation R on set of all real numbers is
reflixve, symmetric, antisymetric and/or transitive where (x,y) E R
iff:

Is it possible to solve either of these problems without using a
graphing calculator or computer?
1.    (X + 2)^X = 7  
2. 3^X^X^X   =  11

x_1, x_2, .... , x_m are the variables and k_1, k_2, ... , k_m are constants
in a system of linear equations.  The aim is to find the solution set to the
system when there are C(m,n) equations where m is the number of unknowns and
n is the number of terms.

I know that the following problem is a parochial concern considering that it applies to U.S. monetary units, but please be welcome to express it in the local system of your interest.
Problem:
What is the smallest number of coins that one can have that will allow the holder to make ...

It's my fisrt Maths assinment and I need help with the triangles section!!! (By the way, I'm aussie so sorry If I "pronounce" things differently. We call it Maths over here.
Here are some questions I need help with:

Does anyone happen to have the Instructor’s solutions manual for Miller & Freund's Probability and Statistics for Engineers (7th Ed.)?  It contains the solutions to the even problems as well, not just the odd ones.  
If so, would someone mind sending it to me?  It would be a HUGE ...

Hi!!
What will be the density function of (X+Y)?
where given density functions are as follows:
f(x)=mu*exp(-mu*x), 0<=x<=infinity.

a) Show that x^2k can be computed using k multiplications.
b) Describe an O(log n) algorithm for computing x^n.
I have had some problems grasping Big O notation...part of it makes sense, and part of it doesnt
