How many trig. functions are there?

>> No.5218104

elementary trig functions? i would say just one, the imaginary exponential. but of course you can make an infinite number of trig functions with elementary ones.

>> No.5218108

just one, e^x

>> No.5218110

Infinitely many.

F(x)=sinx, trig function right?

F(x)=sinx+1, SHAZAM!

protip: keep adding ones for infinite trig functions!

One Trig Function to rule them all, One Trig Function to derive them,
One Trig Function to bring them all and in the complex field bind them.

Only one function on my trig and it's a license to kill.

well all you really need is sin and cos, since all others can be derived from them. i can't speak of hyperbolic functions though because i don't know them

haha well done

For those of you who don't know what these guys are talking about, Google 'Euler's formula.' It's really cool stuff.

Since tan(θ)=sin(θ)/cos(θ) right?

>> No.5218161

how is sin and cos 2 different ones?

>> No.5218195

>>5218123
sin(x) = cos(x+pi/2)
You don't need both.
