It's always a brat to differentiate/integrate it due to the sign change. Why can't it be more like sine?

as in cos θ = sin (θ + π/2) = sin (π/2 - θ)?Nikitin said:It's always a brat to differentiate/integrate it due to the sign change. Why can't it be more like sine?
I remember that in a very silly way. When do 1 over, sin becomes c[STRIKE]os[/STRIKE] and cos becomes s[STRIKE]in[/STRIKE] so we get csc for 1/sin and sec for 1/cos.jtbell said:The ones that I hate are sec(x) and csc(x). I can never remember which one is 1/sin(x) and which one is 1/cos(x), and I always have to look it up.

I'm not sure they their relationship is that healthy, though.
Strangely, while sine's love for cosine is zero, cosine's love for sine is at its maximum, meaning cosine is constantly doing incredible things to woo sine...
Which actually works, except all that wooing is kind of pain, plus, once sine loves cosine, is it really necessary to keep doing all that wooing? In fact, sine is kind high maintenance and and by time sine's love for cosine is at its max, cosine doesn't really care that much for sine.
In fact, sine is kind of high maintenance and whiny. Eventually cosine begins to resent sine and treats sine kind of badly - even very badly, eventually! Which leaves sine confused, wondering if she likes cosine at all.
In fact, she begins to actively hate cosine. And, you know, once the clinginess is gone, cosine begins to realize that sine is pretty good after all and begins to dislike her a lot less.
In fact, once sine's hatred for cosine is at its maximum, cosine finally realizes what he's losing. And once cosine stops treating sine badly, she begins to quit hating him.
In fact, with enough wooing to make up for his insensitivity, sine finally quits hating him at all and thinks maybe they can still be friends.
In fact, she starts to remember why she liked him in the first place. And their relationship starts anew.
Except, you know, sine really is kind of clingy and definitely high maintenance. And cosine begins to remember why their relationship went bad in the first place...
... and on and on they go. They just never learn.
