if `f(X) = sinx + cosx` , then `(f(x) + f(-x ))/(f(x)-f(-x))= ?`

If f(x)=sinx+e^x , then f''(x)

If f(x)=sinx+e^x , then f''(x)

f(x)=sinx+cosx+3 . find the range of f(x).

f(x)=sinx+cosx+3 . find the range of f(x).

f(x)=sinx+cosx+3 . find the range of f(x).

f(x)=sinx+cosx+3 . find the range of f(x).

Sometimes functions are defined like f(x)=max{sinx,cosx} , then f(x) is splitted like f(x)={{:(cosx, x in (0,(pi)/(4)]),(sinx, x in ((pi)/(4),(pi)/(2)]):} etc. If f(x)=max{(1)/(2),sinx} , then f(x)=(1)/(2) is defined when x in
