Question 1

Paper 1, no calculatorMedium6 marks

In Figure 1, the solid curve is $y=g(x)$ The dashed line is its tangent at $P$ where $x=0$

(a)

Using Figure 1, write down the values of $g(0)$ and $g'(0)$

[2]

(b)

The function $F$ is defined by

F(x)=\frac{e^{g(x)}}{x+2}.

Determine $F'(0)$ giving your answer exactly.

Question 2

Paper 1, no calculatorMedium6 marks

The positive solution $y$ of

\frac{dy}{dx}=\frac{2x}{y}

satisfies $y(1)=1$ for $1\leq x\leq 2$ An Euler estimate is made using a step length of $\frac12$

(a)

Write down the Euler estimate for $y\left(\frac32\right)$

[1]

(b)

Hence, write down the Euler estimate for $y(2)$

[1]

(c)

Determine the exact value of $y(2)$ by solving the differential equation.

[3]

(d)

Hence, state whether the estimate in (b) is an overestimate or an underestimate of the exact value. Justify your answer.
