1. The problem statement, all variables and given/known data

Express the integral as a limit of sums. Use right endpoints. Do not evaluate the limit.
$$\int$$sin(x$$^{4}$$dx from 0 to 6
2. Relevant equations

$$\sum$$f(xi)$$\Delta$$x

3. The attempt at a solution

What I'm unsure of here is what exactly the question is asking. How far do I go? Is simply saying that Lim x --> $$\infty$$$$\sum$$sin(2i/n)$$^{2}$$ sufficient?

From the fact that it mentions "use right endpoints", it is asking you for the general form of a Riemann sum of the integrand over a rectangular partition of the interval [0, 6].
