may i know how to do Q1 & Q2 ? thanks alot !

Q1. A particle is moving along the curve whose equation is When the particle is at the point po - (2.5, 1.00329), the x-coordinate is increasing at the rate of 8 units/s. (a) At what rate is the y-coordinate of the point changing at that instant? (b) Is the particle rising or falling at that instant? (c) Plot the curve using suitable software for o s . s. 10, 0 3 )2 10. Also plot the point po on the same figure to verify your answer in part (b). Q2. A curve is described by the following parametric equation. 3t 1 / 23 (a) Find the coordinate of the extrema of the curve (b) Identify using suitable test whether the extrema obtained in part (a) is a maximum or a minimum. (c) Plot the curve and indicate the extrema on the same plot
