1. The problem statement, all variables and given/known data I understand the setup for finding the slope, but always get confused whether I've fully simplified when trig identities get involved. 2. Relevant equations My dy/dx is 4sin(θ)cos(θ) -2csc2(θ) which I simplified to just (-2sin(θ)cos(θ))/(csc2(θ) Does that simpify to anything better than the way I have done it? 3. The attempt at a solution Once I simplify the above expression fully, I know how to plug in the point to find the equation. Thanks so much!
