if f(x)= sinx + cosx for 0 < x < pi/2

At what points, the function f(x)=sinx-cosx,0ltxlt2pi , attains local maxima and minima.

The function f defined by f(x)=(4sinx-2x-xcosx)/(2+cosx),0lexle2pi is :

If y=(sin x - cos x)^((sinx-cosx)),(pi)/(4)ltxlt(3pi)/(4) , then find (dy)/(dx) .

Find the intervals in which f(x)=sinx-cosx , where 0ltxlt2pi , is strictly increasing or decreasing.

If f(x)=(1-cosx)/(1-sinx)," then: "f'((pi)/(2)) is

If f(x)=|cosx-sinx| , then f'(pi/2) is equal to

If sinx - cosx = 0, 0^@ltxlt90^@ then the value of (secx +cosec x)^2 is: sinx - cosx = 0, 0^@ltxlt90^@ तो (secx +cosec x)^2 का मान है:
