If f(x)=(x^(2)-1)/(x^(2)+1) prove that f((1)/(x))=-f(x)

If f:R rarr R such that f(x)=(4^(x))/(4^(x)+2) for all x in R then (A)f(x)=f(1-x)(B)f(x)+f(1-x)=0(C)f(x)+f(1-x)=1(D)f(x)+f(x-1)=1

If f'(x)=(1)/(x)+(1)/(x^(2)+1) and f(1)=(pi)/(4), find f(x)

If f(x)=(4^(x))/(4^(x)+2) , then show that f(x)+f(1-x)=1

If f(x)=(4^(x))/(4^(x)+2) , then show that f(x)+f(1-x)=1

f(x)=(2x+3)/(3x+2), then show that f(x)*f((1)/(x))=1. if f(x)=4, then show that f(x+1)-f(x)=f(x)

Let f(x)=(4^(x))/(4^(x)+2), and given that f(x)+f(1-x)=1 then f((1)/(1997))+f((2)/(1997))+f((3)/(1997))+....+f((1996)/(1997))

Find the domain of the following following functions: (a) f(x)=(sin^(-1))/(x) (b) f(x)=sin^(-1)(|x-1|-2) (c ) f(x)=cos^(-1)(1+3x+2x^(2)) (d ) f(x)=(sin^(-1)(x-3))/(sqrt(9-x^(2))) (e ) f(x)="cos"^(-1)((6-3x)/(4))+"cosec"^(-1)((x-1)/(2)) (f) f(x)=sqrt("sec"^(-1)((2-|x|)/(4)))

If f(x)=x^(2) , then evaluate : (f(x+1)-f(x-1))/(4x)
