 using cosh(x) ? tommy1729 Ultimate Fellow Posts: 1,370 Threads: 335 Joined: Feb 2009 11/19/2011, 11:56 PM no , im not kidding , apart from my sinh method im considering a cosh method. although it might be more complicated or speculative. it might be insightfull to plot things. consider exp(1/e) R. replace x by f(x) and let g(x) be the super of f(x). then we get a difference equation for g(x). we solve that difference equation , now we go from g(x) to f(x) or we find the taylor for f(x) from the equation ( or both , in programming ). similar to the sinh method : since f is close to 2*cosh(ln(b)*x)) and 2*cosh(ln(b)*x) is close to b^x , we have a new method. « Next Oldest | Next Newest »
