Good afternoon,

Please could someone check my answer to the following equation. I could not get it to display correctly so I have attached an image screenshot of the equation

My answer comes to 0.386

My answer comes to 0.386

Is that:

sin(39^o) or sin(39 rad)

Assuming you meant sin(39^o) - I do not get 0.386 as the answer.

please share your work - step-by-step.

Sorry, it is Sin39°

Hmmm, OK thanks. this is what I have so far

How did you get 6293.2 in the denominator - check it again!

I find that the denominator is correct, but the two other calculated values in #4 are rounded improperly. My main concern at that point is that the number of significant digits is inconsistent. (And I'd do all this without copying and rounding, to avoid rounding errors.)

There are a number of small errors, but my answer is in the vicinity of yours.

Correct - I checked my calculations and I had looked at the wrong cell.

So apart from rounding errors, I am on the right lines. Thank you
