Learn your calculator (example 4) Imagine we wish to evaluate the quantity (17.2meter/second)229.80meter/second2sin40 . Start by verifying the sine function operation and that the angle units of the calculator are set to degrees by confirming sin90 comes out to 1. Common ways to set angle units are with a MODE or DGR key. On some calculators you enter the trigonometric operator first and then the angle (sometimes followed by a closed parenthesis), while on others you enter the angle first and then the trigonometric operator. Finally, once you've completed this, use your calculator to evaluate the original expression, which should come out to 23.5meter . Learn your calculator (example 5) Imagine we wish to evaluate the quantity arctan(7.00meter4.00meter) . Start by verifying the arctangent function and that the angle units of the calculator are set to degrees just as above by confirming arctan(1) comes out to 45. Note that this function will likely be written as tan1 on your calculator. Finally, once you've completed this, use your calculator to evaluate the original expression, which should come out to 60.3, then try the last two problems. Part C - Projectile motion A student solving a physics problem for the range of a projectile has obtained the expression R= v20sin(2)g where v0=37.2meter/second , =14.1 , and g=9.80meter/second2 .
