I'm not sure whether to use half angle formulas... Yup, I'd try that! Feb 20, 2008 #3 Architeuthis Dux 883 0 I would approach this problem by first identifying the given function f(x,t) = sin(t)*sin(x) and its desired form f(x+t)+g(x-t)....
#NUM error - The #NUM error shows up when you try to use invalid numeric values in formulas, like square root of a negative number. #N/A error - The #N/A error happens when a value is not available for a formula or found in a given cell range, for example in the VLOOKUP or MA...
The PI function can also be used to convert angle degrees to radians. As shown in the screenshot below, in range B6:B14, there is a list of angel degrees, to convert these angle degrees to corresponding radians, you need to: Select a blank cell, enter the following formula and press ...
