## Homework Statement

Find the slope of the tangent line to the give polar curve at the point specified by the value of theta

R = 1/θ, θ = π

## Homework Equations

Slope of a polar equation is (dR/dθsinθ+Rcosθ/dR/dθcosθ-Rsinθ)

## The Attempt at a Solution

Using my calculator, I plugged π for θ, -.101 for DR/Dtheta (after differentiating R) and R = 1/π

I got π/12 as my answer, but the correct answer is -π. Why am I off by a factor of 12?
