Derivatives of arctan
WebThere is a nice method to get the derivatives of all orders of arctan: write 1 1 + x 2 = 1 2 i ( 1 x − i − 1 x + i) and blindly differentiate as if i ∈ R. Of course this can be made rigorous. ADD A slick solution is the following: 1 1 + x 2 = ∑ k = 0 ∞ ( − 1) k x 2 k It follows (by uniqueness of representation) that if f ( x) = 1 1 + x 2, WebDerivatives of inverse Trig Functions. First of all, there are exactly a total of 6 inverse trig functions. They are arcsin x, arccos x, arctan x, arcsec x, and arccsc x. However, some teachers use the power of -1 instead of arc to express them. For example, arcsin x is the same as \sin^ {-1} x sin−1x.
