Show that the function ` f(x) = |sinx+cosx|` is continuous at `x = pi`.

Show that the function f(x)= |sinx + cos x| is continuous at x= pi

Show that the function defined by f(x) = |cosx| is a continuous function.

The function f(x)=(sinx)/(sinx-cosx) is discontinuous at -

The function f(x)=sinx+cosx will be

Show that the function f(x) defined by f(x)=sin(cosx) is a continuous function .

If the function f(x) = (1-sinx)/(pi-2x)^2 , x!=pi/2 is continuous at x=pi/4 , then find f(pi/2) .

If f(x) = -4sinx+cosx for x =pi/2 is continuous then

Show that the function f(x)=cot^(-1)(sinx+cosx) is decreasing on (0,\ pi//4) and increasing on (pi//4,\ pi//2) .
