Scientific Calculator in JS *resolved*

I've been trying to make an advanced calculator in JS. but I got stuck when I realised that I don't know all the advanced function. I know they exist but not how to use them. So in JavaScript what are the keywords for:

• Sin
• Cos
• Tan
• Sin^-1
• cos^-1
• Tan^-1
• square root
• cube root
• X root
• log
• ln
• pi
• e

• Sin sin()
• Cos cos()
• Tan tan()
• square root sqrt()
• cube root pow(x,1/3)
• X root pow(x,n)
• log log()
• e (Exponent?) exp()

Rest... :ehh:

thx alot, with e I meant the constant, worth 2.71 something
What the thing for Pi too?

Never mind found it myself.
