find the length of the curve r=4cosθ, from θ=0 to θ=3π/4
Added by Melissa J.
Step 1
This is given by: L = ∫√(r^2 + (dr/dθ)^2) dθ where r is the polar function and dr/dθ is its derivative with respect to θ. In our case, r = 4cosθ, so we need to find dr/dθ: dr/dθ = -4sinθ Now we can substitute these into the equation for the length of the Show more…
