અમુક $a, b$ માટે,ધારો કે $f(x) = \left|\begin{array}{ccc} a+\frac{\sin x}{x} & 1 & b \\ a & 1+\frac{\sin x}{x} & b \\ a & 1 & b+\frac{\sin x}{x} \end{array}\right|, \quad x \neq 0$. જો $\lim_{x \rightarrow 0} f(x) = \lambda + \mu a + \nu b$ હોય,તો $(\lambda + \mu + \nu)^2$ ની કિંમત શોધો:

જો $f(x) = \left| \begin{array}{ccc} 2 \cos^2 x & \sin 2x & \sin x \\ \sin 2x & 2 \sin^2 x & -\cos x \\ \sin x & -\cos x & 0 \end{array} \right|$ હોય, તો $\int_0^{\frac{\pi}{4}} (2|f(x)| + 5f'(x)) \, dx$ ની કિંમત શોધો.
