Q1. Find the derivatives y(x)= dy/dx of functions y(x) listed below, simplify the answers, and plot the relevant graphs.
Do it in 2 steps: (1) firstly, do not simplify y(x) before evaluation of y'(x) and simplify y'(x) after evaluation; (2) then, for
verification, simplify y(x) and, after simplification, evaluate y(x) and compare it with the result of step (1).
(Program Outcomes: PI-P4, P6-P8)
(a) y(x) = x² (x-1)²
(4 points)
(1) Direct evaluation:
y'(x)=
(2) Simplify: y(x)=
Verify: y'(x)=
(b)
y(x)=
x²-1
x+1
(1) Direct evaluation:
(2) Simplify: y(x)=
(c)
y(x) = sin²(x)
y'(x)=
y'(x) =
Verify: y'(x)=
