2. 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

Are you by any chance religious?

Okay explain to me how you would go from to ??? What identity are you using?
6. if there is no cement then remove the bricks but if there is then i recommend using a hard faced tool such as a hammer. Hope this helps

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

Better start liking it because you're just at the start of the year!

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

lol.... I'm not zac

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

Yes.

Anyway, back to the maths.

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

Yes.

there are no genders when in the world of mathematics

Use the identity to get sin squared in terms of cos squared.
