ab/m ( -2m^(-2) / ba  +  3m / a^(-1) b  )

than

ab/m (-2/abm^(2) +  3am/b) < handle negative exponents
ab/m * -2/abm^2 + ab/m * 3am/b < distribute
now i have to do......

given that 0 degrees <_ x < 360 degrees , solve the following equation :

cos x - sqrt(1 - cos^2 x) = 0

## #7 Re: Help Me ! » Equation of the line » 2007-01-04 10:03:22

i get it ....
m = (-2 - 3) / (0 - 4) = 1.25
y - y1 = m (x - x1)
y - 3 = 1.25 ( x -(-2))
y - 3 = 1.25 ( x + 2)
y = 1.25x + 2.5 + 3
y = 1.25x + 5.5 this is the equation!

## #9 Re: Help Me ! » Terms » 2007-01-04 09:44:40

ok so look at what i did:

(x+y)^7
1st term > 1(x)^7
2nd term > 7(x)^6 . (y)^1
3rd term > 14(x)^5 . (y)^2

thats all i need right?

if a certain parabola has its vertex at (2,-1) and its focus at (2,1), write its equation and graph.

(h,k) = (2,-1)
h = 2  k = -1
focus (h,k + p) is (2,1) so k + p = 1
k = -1  p = 2

y - k = 1/4p( x - h)^2  < equation
y - (-1) = 1/4(2)  (x - (2))^2  < substituted
y = 1/8 ( x - 2)^2 - 1 < solved

## #21 Re: Help Me ! » Equation solving wht next? » 2007-01-02 03:34:39

soooooooo by using the reference i did:
9x^2 + 3x - 8 = 0
x^2 + 3/9x - 8/9 = 0
x^2 + 3/9x = 8/9
x^2 + 3/9x + (3/81)^2 = 8/9 + (3/81)^2
(x + 3/81)^2 = 8/9 + (3/81)^2
(x + 1/27)^2= 8/9 + 9/6561 = 649/729
(x + 1/27)^2 - 649/729 = 0
27(x + 1/27)^2 - 649/729 = 0
27(x + 1/27)^2 = 649/27
(x + 1/27)^2 = 649/729
x + 1/27 = +- sqrt(649/729)
x = 1/27 +- sqrt(649/729)
x = -703.5 ... and -0.906....

correct
