Answer:
=SUM(C2:C4, C7)
Step-by-step explanation:
In excel 'C' represent the cell ( intersection of row and column ),
Also, '=sum( )' represents the function of addition in the excel,
Also, when we operate all consecutive cells from to
Then under the function formula we write
And, when we operate a cell with non consecutive cell
Then under the function formula we write
Hence, C2+C3+C4+C7 can be written as,
=SUM(C2:C4, C7)

Answer:
Step-by-step explanation:
Remember that
If angle t belong to the First Quadrant
then
The value of sin(t) and cos(t) are positive values
we know that
---> by trigonometric identity
we have
substitute
