can someone show me how to solve this identity:
csc^4(x)-cot^4(x)=(2csc^2)-1
note: you can only work on one side
additional info: 1+cot^2(x)=csc^2(x), 1+tan^2(x)=sec^2(x)

I am having problems with this one
You have left out an x on the right hand side,
Could you just double check that the rest of the question is written down correctly.
Thanks.

how do you convert m/s to rad/sec

If you know the radius in metres

then x m/s = x/radius radians/sec

Melody15 нояб. 2013 г.

+118723

You can't unless you know the radius.
radians is an angular measure.

First multiply both sides by 4 then it might be easy.
