Find the polar equation for the cartesian curve x^2-y^2 = sqrt(x^2+y^2)
cestrela7 [59]

ANSWER:

r = \frac{1}{cos2(theta)}

Explaination:

Convert the given curve into the the polar form.

x = rcosθ

y = rsinθ

in f(x,y) = (x²-y²) - √(x²+y²) = 0

put the values of x & y in given curve equation.

We get at,

g(r,θ) = (r²cos²θ - r²sin²θ) - √(r²cos²θ + r²sin²θ) = 0

g(r,θ) = r²(cos²θ - sin²θ) - √r² = 0

We know that,

cos²θ - sin²θ = cos2θ

g(r,θ) = r²(cos2θ) - r = 0

Solve for r

Finally we get:

r = \frac{1}{cos2(theta)}

Find the slope of the line.
ladessa [460]

Answer:

2

Step-by-step explanation:

we know the line goes through the origin, so we have point (0,0). next, find another point the line goes through. for example, point (2,4)

the slope formula for points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1). plug in the 2 points to get (4-0)/(2-0) = 4/2 = 2
