Consider the function `f:[0,pi/2]rarrR` given by `f(x)=sinx` and `g:[0,pi/2]rarrR` given by `g(x)=cosx`.
Is `f+g` one-one?Why?

Consider the function f:[0,pi/2]rarrR given by f(x)=sinx and g:[0,pi/2]rarrR given by g(x)=cosx . Show that f and g are one-one functions.

Consider a function f : [0, pi/2] rarr R given by f(x) = sin x and g : [0, pi/2] rarr R given by g(x) = cos x. Show that f and g are one-one, but f + g is not one-one.
