Parametric & Rectangular Equations, Slope & Concavity
I am in a fast-paced Calculus course where I must learn new concepts each week; I find it challenging to grasp the concepts while remaining on-pace and I am experiencing great difficulty. I am really finding it difficult to grasp the concept of Parametric & Rectangular Equations, Slope & Concavity, and Tangent Lines.
Specifically, I need your help in understanding:
1. Finding the slope and concavity of given parameters.
2. Finding the equations of tangent lines.
3. Creating curves for parametric equations.
My school has been unable to provide me with a suitable tutor; I’ve also attempted to obtain my own outside of the school.
I would appreciate your assistance on the attachment; I would also appreciate any points you can provide to help me understand the concepts more clearly. I really want to understand the material, so your explanations are vital; please.
