|Enter the formula
in cell C8. Note that
vo and theta are names you defined and
pi() is the built in function for the value
p. And name this cell vox.
Continue entering formulas for the cells C9, C11 and C12 as shown in the figure. C9 is given the name voy and C12 is named delta_t. delta_t is the time step that we will be using to increment the time which will be explained later. Time of flight T gives the total time the projectile is in air before returning to ground again.
No name is given to the cell C11. Note that the formula in cell C12 refers to C11 by its default absolute name.
