Horizontal Asymptote

1. Exponent of numerator is larger than exponent of denominator

2. numerator exponent = denominator exponent --> use LC ratio

3. If denominator exponent is greater than numerator exponent y=0

Vertical Asymptote

Set denominator equal to 0

X-Intercept of fraction function thing

Set numerator equal to 0

Y-Intercept of fraction function thing

Plug in 0 for x

Slant Asymptope

Add once u know

When finding angle between two lines use this formula

tan(θ)=Im2-m1/1+m1(m2)I

θ=π/2

(-r,-θ)

Polar axis

(r,-θ)

Pole

(-r,θ)

cos-θ becomes…

cos+θ

sin-θ becomes…

sinθ

R^2 =

x^2 + y^2

x=

rcosθ

y=

rsinθ

r=

√x^2+y^2

θ=

tan^-1(y/x)
