WebSince tan y=x, the tan ratio opposite/adjacent tells you that your opposite side is x and adjacent side is 1. Now use pythagorean theorem to find the hypoteneuse, which is sqrt(x^2+1). Then form cos y= 1/sqrt(x^2+1) and sub. it back into the above formula, squaring it to give you 1/(1+x^2). WebMaximum/minimum For turning points: f '(x) = 0 Let x = a be a solution for the above If f '' (a) > 0, then a is a minimum point If f ''(a) < 0, then a is a maximum point For points of inflection: f" (x) = 0 Let x = b be a solution for the above Test for inflection: f (b-h) and f (b + h) Change sign or f '"(b) ≠ 0 if f '"(b) exists. 1 2 1 2 1 ...
