Find the maximum value of

To find: the maximum value of


Firstly, we need to find the value of determinant and then find its maximum value



Apply C1→ C1 – C2 and C2→ C2 – C3






Multiplying and dividing by 2:




{∵ sin 2θ = 2 sin θ cos θ}


Value of sin x lies between -1 and 1


∴ The maximum value of sin x is 1 where x is any angle


The maximum value of


Hence, the maximum value of
