On the interval $\left(0,\frac{\pi }{2}\right),$ the function $\log \left(\sin x\right)$ is

The interval for which the given function $f\left(x\right)=2x^3-3x^2-36x+7$ is decreasing, is

The function $f\left(x\right)=2x^3-3x^2-12x+5$ has a minimum at $x=$

The sufficient conditions for the function $f:R\to R$ to be maximum at $x=a$ will be

The minimum value of the function $f\left(x\right)=7-20x+11x^2$ is

The minimum value of $2x^2+x-1$ is

The function $f\left(x\right)=2x^3-3x^2-12x+4$ has

The function $y=1-\cos x$ is maximum, when $x=$
