What will be the minimum value within a given range? GATEFORUM_MOCKS
Which of the following is the right Procedure to get the minimum for f(x)? Procedure 1: This is a closed interval, so we will have to calculate the value including and between [0,π/2]. To get critical ... we supposed to substitute each value in f(x) from options to check which gives the minimum? Which Procedure is right?
