I've got some really bad news. I found 3 more questions on the next page that I'm meant to do:
6. sin^2x/1-cosx = 1+cosx
7. 1/cosx + tanx = cosx/1-sinx
8. tanxsinx/1-cosx = 1 +1/cosx

I'm gonna have a go but I'm sure I'll be back

Okay explain to me how you would go from

1-\cos{x}

\sin{x}

??? What identity are you using?

Obviously the bricks are fixed. Why would he have asked for help if there was no cement?

For Q6, can you do to the numerator?

the real question here is are you assuming the gender of the person asking the question, gender fluidity is a real thing "notnek" and I would've thought you would understand that very well - not impressed

Use an identity for it. Express it in terms of cosx.

Oh my I'm so sorry RDKgames! Please excuse my mistake but I must admit I don't get what you mean about expressing it in terms of cosx
