Help

[wise fossil]

Can someone prove it in a simple way

[modern lance]

1/sin^2xcos^2x=(sin^2+cos^2)/(sin^2cos^2)=1/cos^2+1/sin^2=sec^2+csc^2

@wise fossil

[wise fossil]

Wait can u show u got from 1st step to second

[modern lance]

Sin^2x+cos^2x=1?

[wise fossil]

OMG

Ur so smart

Wait I never thought to do that

[wise fossil]

Wait how’d u get from second step to third

Oh nvm I get it

Tysmmm

[modern lance]

I just separated the paranthesis
It s sin^2/(sin^2cos^2) + cos^2/(sin^2cos^2)

[modern lance]

Welcome!

[wise fossil]

Wait so @modern lance can u separate paranthesis

When it’s like a/b+c

And can u do it when it’s b+c/a

[modern lance]

You have (b+c)/a=b/a+c/a
a/(b+c) is not a/b+a/c

Ok thank you
