Math (Trig. Identities) help needed

[redsox985]

I was given this problem, along with many others, for a summer assignment. I can not seem to figure it out and was wondering if anyone would/could help me. If you'd rather work it out on paper and take a picture or scan it, than try to type it all out, that's great.
Thanks

I learned them in school, but im on three months hols at the moment so i forgot them, i will have a look back for ya

That's what dilemma I'm in. I'm on summer vacation and procrastinated like a champ and now I forget.

a.) Tan(x^2)+x=sec(x^2) I think.

 

[redsox985]

You sound a bit shaky on that one. I think I'll wait for KieranM or someone who can convince me it's along the lines of correct. Convincing BS is better than regular BS.

Its been a while since differentiation. Cant say i really use them in the real world haha.

 

[redsox985]

Thank you. I wish my math teacher would believe that. He says he uses them everyday (that's cause we b**** while he's teaching them. What a coincidence.)

 

[brendonv]

Well to be fair, he would use them everyday. I mean, he's a maths teacher.

 

[redsox985]

That's the coincidence. Wrong person to b**** to.

I'm sure they have a use somewhere, but when it comes to math past basic algebra, you have to show me the application before I can do the math. Like static stress calculations aren't a problem for me, but make me do anything past really basic trigonometry and my brain start pouring out my ears. What redsox985 posted looks like mandarin to me.
