Okay, we have (1- i)/(√3 - i).

I did exactly like I'm supposed to and got:

√2 [ cos (√2/2) + i sin ( -√2/2) ]
------------- ------------- --------------
2 [ cos (√3/2) + i sin ( -1/2) ]

=

√2 [ cos (7pi/4) + i sin (7pi/4) ]
------------- ------------- --------------
2 [ cos (11pi/6) + i sin (11pi/6) ]

And now I have to divide the √2 by 2 and subtract in the following manner:

[ cos (7pi/4 - 11pi/6) + i sin (7pi/4 - 11pi/6) ]

and I get:

√2/2 [ cos ( - pi/12) + i sin ( - pi/12) ]

Now before I go and do out the sum/difference of two cos and sin, etc. because I can't find a trig table with -pi/12, can someone just tell me if my answer is right so far?

Thank you so much! I'll pick a best answer TODAY!!!!!!!

Here's the first problem I did and don't believe it's right. Could you please help me:

∫sec^2x√tan x dx
u=tan x=sin x/cos x
du/dx=sec^2x
du=sec^2x dx

1/2∫u^1/2 du
1/2√(2/3)u^3/2+c
1/2√(2/3)tan x^3/2+c

If this answer is incorrect, can you please show me the right way of doing this problem. This is a hard section to understand!

Points A, B, C are on a line in the order ABC. What can be said about the distance AC in relation to the distance AB, BC?
AB - AC = BC
AB + BC = AC
AC + BC = AB


A, B, C are points with B in the line AC. What can be said about the distance AC in relation to the distances AB, BC?
AB + BC = AC
AB - AC = BC
AC + BC = AB

I don't understand how you find the answer to these. Can you please explain? Thanks in advance!

A college arena sells tickets to students and to the public. Student tickets are $8 each and general public tickets are $32 each. The college reserves at least 5,000 tickets for students. The arena seats 18,000.

let s= the # of student tickets
let p= the # of general public tickets

Write a system of inequalities to represent the number of tickets sold.

Can you help me with writing the inequalities?

I cant make it on the computer but its a negative sign and the two and a little three. I know that the two and the three represent two to the third power, but is it negative two to the third power or the opposite of two to the third power. I also know that it would not change the answer, but i need to know how you would say it.
