Question

Solve for x! f(x)=2x-4sin(x)

Answer 1

what way do you mean?
you have a function in terms of x...to solve for x would yield the inverse function

however a linear combined with trig cannot be separated algebraically

Answer 2

oops. 0=2x-4sin(x)

Answer 3

So this is not possible??

Answer 4

no its possible, just not algebraically

Answer 5

Woah 0_o

Answer 6

for example, you could use Newton's method to approximate the zeros of f(x) using calculus

\[\large x_{n+1} = x_{n} - \frac{f(x_{n})}{f'(x_{n})}\]
