Question

The expression ( cot^2x/1-sin^2x is equivalent to ??

Answer 1

You have not written what you intend. Please remember your Order of Operations and use parentheses where necessary.

Answer 2

cot^2x/ 1-sin^2x

Answer 3

sorry there's no parentheses in the question

Answer 4

No, try cot^2x/ ( 1-sin^2x ).

It is not the same in print as it is inline. You must see the difference and compensate.

Answer 5

Change cotangent to cos(x) / sin(x)
and change 1-sin^2(x) to cos^2(x)

Answer 6

what should I do after that ? please help

Answer 7

Did you do it? \(\dfrac{\cos^{2}(x)}{\sin^{2}(x)}\cdot \dfrac{1}{\cos^{2}(x)}\)

Are you sure you can't come up with something?

Answer 8

I got you :) Thank you sooo much

Answer 9

I did it wrong the first time

Answer 10

Rule of thumb -- If you don't see it right away, change it to sine and cosine and hope...

Answer 11

I'll remember that rule

Answer 12

Don't forget the "hope" part. There is always hope! :-)
