: There is a heavy emphasis on integration and differentiation. For instance, questions involve finding the exact volume of solids generated by revolving regions between curves around the x-axis, which requires mastery of trigonometric and exponential integration.

$$ \fracx^2-4x+1 = x $$ $$ x^2 - 4 = x(x+1) $$ $$ x^2 - 4 = x^2 + x $$ $$ -4 = x \implies x = -4 $$ The intersection point is $(-4, -4)$. Wait, we are looking for the region bounded by the y-axis ($x=0$). The intersection at $x=-4$ is on the left side. The region specified is bounded by $C$, $y=x$, and the y-axis.

Geometric applications involving the area of triangles and point projections in 3D space. Question 3: Maclaurin series expansion involving e to the x-th power Question 6: : There is a heavy emphasis on integration

A differential equation question appeared, likely modeling a physical scenario (like cooling or population growth). The integration required separation of variables, but the initial algebraic arrangement was the stumbling block. Wait, we are looking for the region bounded
