SOLVE FOR X

x=±∞

Uh, I don't have an equation.

You can now imagine what a pain in the math my Trigonometry honors class is like. Later on in the chapter I get nonsense like "Find the three cube roots of root8(cos135 + i*sin135)". The first step is to turn it into:

root6(8)(cis((135+360k)/3))

Problem:
x

SOLVE FOR X

X

I hated trig.
I'm taking a college algebra duel-credit course at my high school right now and Trig last year was much harder.

i'm taking Algebra 2 next year and then methinks trig/pre-calc junior, then calc.

too lazy to look up my 4-year plan

Pssh, trig's easy stuff.

i is a variable, standing for the imaginary axis (y). You'll need two parts.

INTEGRAL(e^(-x)2)

sryz 4 bump but need more maths.

write 5x - 2 in functional notation.

[dorkdotdan]

Y=5x-2 ?

[Treynolds416]

Y=5x-2 ?

Maybe f(x) = 5x - 2

FYI, this isn't a math problem, this is what you'd call a vocabulary problem

[Elecro]

bump again.

I have a test tomorrow and one of the things I need to know is discrete and continuous data. The book didn't explain it well enough and I'm confused, help pls.

x = x
solve for y
