tan 40-9.8*20^2/(92*16^2*cos^2*40)
Cos of what?
I'm gonna assume it is 40 with the tan
\(tan{40}-9.8(\frac{20^2}{92*16^2*cos^2{40}*40})\)
tan(40)-9.8(20^2/92*16^2*cos(40)*cos(40) *40) = -194075.942
-194075.942
I would have assummed they meant (cos(40))^2 read as cos squared 40 or cos 40 all squared
\(tan 40-9.8*20^2/(92*16^2*(cos(40))^2)\)
That would give 0.555471
But it is a guess at what the cos^2*40 meant
+2592
