Area by Integration - Problem Solving Practice Problems Online

Let $S$ be the area of the region bounded by the curve $y=x^3$ and the tangent line to the curve at $(1,1)$ . If $S = \frac{a}{b}$ , where $a$ and $b$ are coprime positive integers, what is the value of $a+b$ ?

Let $S_1$ be the area of the region bounded by $y=x^2$ and $y=1$ . Let $S_2$ be the area of the region bounded by $y=x^2$ and $y=\frac{7}{8} x^2+k,$ where $k > 0$ . If $S_2=S_1$ , what is the value of $\frac{1}{k}$ ?

Let $S$ be the area of the region bounded by the $x$ -axis and the graph of $y=-k^{19} x^ {18} +k$ , where $k>0$ . What is the value of $152S$ ?

Let $S_1$ be the area of the region bounded by the curves $y=x^2$ and $y=1$ . Let $S_2$ be the area of the region bounded by the curves $y=x^2$ and $y=\frac{1}{m}x^2+\frac{m}{m-1},$ where $m$ is a positive integer strictly greater than 1.
If $a$ and $b$ are coprime positive integers, and $\frac{S_2}{S_1}=\frac{a}{b}$ and $a+b=925$ , what is $m$ ?

The area bounded by the parabola $y=x(6-x)$ and the $x$ -axis is divided into two regions by the line $y=x$ . If $S_1$ is the region above $y=x$ and $S_2$ is the region below $y=x$ , then $S_1 : S_2 = a : b$ , where $a$ and $b$ are coprime positive integers. What is the value of $a+b$ ?
