SECTION 3-6
ans.
a.
Dy/dx=(dy/du)*(du/dx)
Dy/du=3u2
Du/dx=1/2(x)1/2
Dy/dx= 3x*1/2(x)1/2
=3x1/2/2
b.
Dy/dx=(dy/du)*(du/dx)
Dy/du=1/2(u)1/2
Du/dx=3x2
Dy/dx= =3x1/2/2
SECTION 3-7
Ans.
Put x=pi/4 and y=pi/2
Pi/4*(sin(pi)=pi/2*(cos(pi/2)
0=0
Hence the point is
Plotting the curves = 2 2 , = 2 and = 0, we have
We first find the area shaded in blue.
For limits:
2 2 = 2
2 2 = 2
= 1
We take the lower limit as = 0 since it is a constraint in the question and the upper limit as = 1.
