Since F'(0)=1 (that is, the graph of F is tangent to the diagonal at x=0) this fixed point must be neutral. Moreover, graphical analysis suggest that the fixed ... Here is asymptotic at x=0. 50 x=0 is a singder pant. X. Fanx is not defined at x= π/₂ + nπ for NEZ. What about tanx? X. limx→0sinxx=1limx→0cosx−1x=0. ... tanx,ddxcscx=−cscxcotx. 0 − x0)=(x2 − x1)2 . 3. Assume 15 +25 +···+n5 = P(n), where P(n) is ... tan(x + α) tan(x + β) + tan(x + β) tan(x + γ) + tan(x + γ) tan(x + α)=1 . 12 ...
