Find the area between the curves y=x and y=x2
The required area is represented by the shaded area OBAO as
The points of intersection of the curves,y=x and y=x2,is A(1,1).
We draw AC perpendicular to x-axis.
∴Area(OBAO)=Area(ΔOCA)-Area(OCABO)...(1)
=
\[\int_{0}^{1} x \,dx\]-
\[-\int_{0}^{1} x^2 \,dx\]
=[\(\frac{x^2}{2}\)]10-[\(\frac{x^3}{3}\)]10
=\(\frac{1}{2}\)-\(\frac{1}{3}\)
=\(\frac 16\)units
The area of the region given by \(\left\{(x, y): x y \leq 8,1 \leq y \leq x^2\right\}\) is :
If 5f(x) + 4f (\(\frac{1}{x}\)) = \(\frac{1}{x}\)+ 3, then \(18\int_{1}^{2}\) f(x)dx is:
(a) State the following:
(i) Kohlrausch law of independent migration of ions
A solution of glucose (molar mass = 180 g mol\(^{-1}\)) in water has a boiling point of 100.20°C. Calculate the freezing point of the same solution. Molal constants for water \(K_f\) and \(K_b\) are 1.86 K kg mol\(^{-1}\) and 0.512 K kg mol\(^{-1}\) respectively.
