I am trying to work out how to solve the following functions graphically.
On the same axes, draw the graph of $y = \sin x$ ($x$ in radians) and $y = \dfrac{1}{x}$ for values of $x$ between $0.5$ and $1.5$. Use graphs to estimate a value of $x$ such that $x\sin x = 1$.
Explain why when $x$ is large, solutions of the equation $x\sin x = 1$ are given approximately by $x = n\pi$, where $n$ is an integer.
How do I go about graphing different units on the same axes. I thought of using equivalent degrees but that makes the sin graph too large for values $0.5$ and $1.5$. Is this type of problem only for solving with calculators?
Thanks again for all your help.
