Minimum value of expression is obtained when denominator maximizes. hence maximum value of 3 sin@ – 4 cos@ +7 = 5 + 7 = 12 Hence minimum value of original expression is 1/12

Dear Student,
Here a = 3, b = 4 or – 4 (doesn’t matter since squaring it will give the same result)
Now since the expression is in the denominator so we need to find the maximum value of since greater is the denominator lesser will be the value of the original expression.
