The answer to Cot(arc tan x)
I was simply explaining that functions such as cot(x), arctan(x), sin(x), ln(x) etc. are always written without any spaces.Cot(arc tan (x))?
Did you derive that for yourself or take it from somewhere else? It also has an obvious common factor of 2 in the numerator and denominator.I have reached a equation to express cot(x) by cot(2x) and it is not an easy one the equation is this (2cot(2x)+(-)(4cot(2x)^2+4)^0.5))×2^-1
Is this right?
Sorry BvU, I forgot all about your drawing further up. It could've saved me quite a bit of explaining in my last post if I just referred to your diagram.Did you make a drawing again ?
