Write the following as a single trigonometric function

1/2 is a half, and the x value is theta, i wasn't sure how to do it that way. The question i have is this supposed to be 12theta, or should it be 2theta. i'm not sure how to do this.

Thanks

Let's assume it says 12x.

If we set u=12x, the expression becomes

The sine of a double angle formula says:

Can you apply it here?

At the end, remember to write the expression in terms of the original variable x. Good luck! - Jul 14th 2010, 08:46 PMpickslides
