well the problem itself was did not come with identities. what the textbook contains in terms of what we have covered in class i guess are the equations. Added attachment

Homework Statement Simplify the expression Cos(6θ) Simplify means - the angle for all trigonometric functions in your answer is to be only θ. Simplify in terms of sines and cosines Simplify in terms of cosines only Simplify in terms of sines only Homework Equations Basic Trig Identities...

if the balls speed changes thus making it not have equal speed between bounces taking different time how do i go about figuring it out with geometric progression

wouldnt i just go about finding the time by first finding hte total distance in feet, then figure out the time it was in travel by the feet per second it travels. total distance / 32ft/s^2 sqrt of (total distance / (32ft/s^2))

awesome, thanks guys would i go about the same way to figure out the total time in seconds the ball was in motion.

i looked at the wiki page but I am just having some trouble with set up of the equation. i know jeff reid set up an equation for me but i am still having trouble understanding the set up and calculating it.

wouldnt it be like this?? the equation

hmmm soo how would i go about figuring out the clever method to get he sum. I am just having a hard time with this, someone please help.

Bouncing ball distance edit

here are the equations that were presented with the lab. http://img228.imageshack.us/img228/5433/bouncedm1.jpg

Homework Statement Figure out the total distance traveled by a ball bouncing vertically when its dropped from a height of 6 ft above the ground and the time the ball was in motion for. G 32ft/s^2 ball one dropped from 72 inches bounced back up 53 inches with a Coefficient of...

sweet. got it to work finally. thanks man appreciate it. :) { iCount++; } iNum--; }while (iNum>=0);

this is what i could come up with from Rangers little write out

but i also got to decrest 500 to a lesser number 500, 499, 498, 497. i got to use the i-- to soem extent

but i got to Use at least 1 increment operator and 1 decrement operator and 1 compound boolean expression. soo i got to set i=500 then go if --i%5<1 then count++
