If θ is the angle between the curves y=sin x, y =cosx at x=π/4 then tan θ=

A curve passes through the point (2, 0) and the slope of the tangent at any point is x^{2}-2x for all values of x. The point of maximum or donation the curve is

The function f(x) = tan x has

f(x)= x-1/x is

The function f(x)=cot^{-1} x+x increases in the interval
