This conic has a directrix at y = 4, an eccentricity of 1/4, and its focus is stationed at the pole (0,0).
I got r = 4/(4+sintheta)
Did you get that?-you got it right
r = ed /(1 + esin(θ))
here e
An arc-sign perhaps?-Is this a trig question, because it seems youre out to trig us today... LOL
Ah, Pukka Sahib, I submitted ten puns to a pun contest, hoping one would win. Alas! No pun in ten did.

This involves numerology (please try not to send me to some website). I was just wondering- for the sake of a story that I am writing -what your favorite number says about you?
For me, the following
Umm it doesnt come out for me!!!-Need two numbers whose product is 5*(-32)=-160 and sum is 6
16 and -10
so
5x^2- 10x + 16x - 32 = 0
5x(x - 2) + 16(x - 2) = 0
(5x + 16)(x - 2) = 0
so
5x + 16 = 0orx -
1. if x² + y² = 14 and xy = 5, find the value of (x+y)²
2. Given that a + b = 10 and a² - b² = 40, find the value of a - b-1.(x+y)^2 = x^2+xy+xy+y^2
= x^2+2xy+y^2
=14 + 2(5)
= 24
2. this is pretty

Using Greenee Theorem, evaluate the integral under Cof ∫ x^2cosy dx - xdy where C is given by |x|+|y|= pi............Ive been having some trouble with this problem, and if anyone can help it would be
Ok heres, the question:
Evaluate: integral cos^2(5x)*sin^2(5x) dx.
Ive taken about three approaches, and always get (1/80)sin(20x) + C. My book says the answer is (1/8)x - (1/160)sin(20x) + C, and I

ok so 1st problem i need to find n
a=2(a is first term)
r=3 (ratio)
a_n = 118,098
answer is n =11 but i need the steps
so here is my work
2(3)^(n-1) = 118,098
3^(n-1) = 59,049
what is the next step?
