Simplify the following products as far as possible:

I have managed to do the first two (I think they are correct), but the third is causing me problems. I have shown the first two in case they help with the third in any way.

(i)

(ii)

(iii)

After some fiddling around, I can get it down to:

I have no idea if this is correct, and I don't know what to do now. Any help would be appreciated.

Thanks.

Looking at part (ii), would it be possible to use trig idientities in some way, making use of (r² - 1) / r² ?

Simplifying the original expression never even crossed my mind.. I feel quite silly now. I think the look of the question just through me off. Thank you Jane.

Hi H_GUEST;

The term "product" refers to the result of one or more multiplications. For example, the mathematical statement a×b=c would be read "a times b equals c," where c is the product.

For another example 7 * 8 = 56 , 56 is the product of 7 times 8.

Say example what is the product of 1232?

If that is a number then there are no multiplications to yield a product.
