Trig Identities (1 Viewer)

Yes, it is.

Except I chose not to be lazy and actually gave a proper solution.

And Shazer, indeed I am using that identity =)

Thanks Carrotsticks. One more thing the following lines I'm not 100% sure on:

I'm not sure how you go from one line to the next.

Multiply top and bottom by cos.

Since what he is doing is basically multiplying the numerator by 1/cosB, it is the same as multiplying the numerator by 1 and multiplying the denominator by CosB.

EDIT: Or what Realise said lol

Damn you carrot (so slow) - I will post mine anyway.

I go away for 5 minutes to work it out and there are like 20 posts on the topic.

Multiply top and bottom by cos.

Thanks. That makes sense.

I just find it difficult to approach these questions and I never know if I am actually getting anywhere or not.

Thanks for all the help everyone.

With lots of practice, you'll pick up different approaches and notice what to do when you see particular questions =)

Props to enoilgam for the effort, still got it

Yeah, maths is something I really need to dedicate more time to, because it'll play a big part in my ATAR.

 

[Carrotsticks]

Haha okay guys, I think that's enough fun for this thread. Just relevant stuff now please =)

That but since I notice you're doing standard english, I think you should try maximise mark there.

Just post questions whenever you have them and we'll do our best to help

 

[HSC2014]

is cos^2 A and (cosA)^2 the same thing??

 

[deswa1]

Yep

Yes that as well as Economics. :'( I'm screwed.
