Sum of all integer values in the range of \( f(x)=5+\left(\cos ^{-1} x\right) \) |
|
Answer» Principal value rang of cos-1x is [0, π] \(\therefore\) Range of f(x) = 5 + cos-1x is [ 0 + 5, 5 + π] = [5, 5 + π] = [5, 8.14] Integer value in the range of f(x) = 5 + cos-1x are 5, 6 \(\therefore\) Sum of all integer value = 5 + 6 + 7 + 8 = 26 |
