[ptc-5029428]

Dear Expert,

i'm working on an equation relates to the differentiation in a range of value.

The problem is i could not get the result for each value within the range unless i manually insert it.

here i attached my working spreadsheet for better understanding.

Appreciate your help and guidance.

Thank you

Regards
