Q.
(i) Sketch the curve y = 2 sin x for 0 <= x <= 2pi. [1]
(ii) By adding a suitable straight line to your sketch, determine the number of real
roots of the equation
2pi sin x = pi- x.
State the equation of the straight line. [3]

What are the question marks ? Simply give year and the session.
Sea Lover:
guys I need someone to explain to me this question ,it's in ocober /november 2010 varient 2 question 7(iii).
The function f is defined by
f(x) = x^2 ? 4x + 7 for x > 2.
The function g is defined by
g(x) = x ? 2 for x > 2.
The function h is such that f = hg and the domain of h is x > 0.
(iii) Obtain an expression for h(x).
In the markscheme the answer is x^2 +3, can someon explain it to me and how to get it?
