Name: amandeep grover Who is asking: Teacher Level: Secondary Question: solve the equation sin x = x/10 Hi Amandeep, I like this question because it makes us think about what we mean by "solve". When we ask students to solve we expect them to use the general quadratic and simplify to get
For sin x = x/10 I know one solution, x = 0 and from the diagram I know there are 6 more but I don't know a nice way to exprress them. I can approximate the solutions to as many decimal places as you might want but I can't express the solutions in a simple algebraic or trigonometric exprression.
Cheers,
