how to find the amplitude of sin or cos? please help???

Question

anonymous · Answer

half the overall height maybe?

anonymous · Answer

if its a graph its easy to tell, if its an equation its a little different to tell

anonymous · Answer

first get its 
angle or argument than put the value of it for sin or cos 

like sin30 =1/2
cos60=1/2...etc

anonymous · Answer

if its an equation do i just graph it, and just see what the highest number for y is?

anonymous · Answer

if its an equation .... you can look for a certain factor:

y = A trig(p(x-phase))

anonymous · Answer

|A| is the amplitude

anonymous · Answer

for example:  -300 sin(3x-pi/4)

the amp is 300

anonymous · Answer

yup

anonymous · Answer

ok so if it was y = 5sin2x then the amplitude would be 5?

anonymous · Answer

yep

anonymous · Answer

ok thanks

anonymous · Answer

oh wait i have one more question

anonymous · Answer

how do i figure this out? 1.	You (safely) bungee jump from a 200-feet tall bridge in your town. Your distance above the water's surface depends on the time since you jumped. Sketch a reasonable graph.

anonymous · Answer

thats the only answer i know :)  so it better be the same question lol

anonymous · Answer

hmm,  assuming that 100 is our amplitude, and we start at 200 ...

-100 sin(t) + 100 seems reasonable to me

anonymous · Answer

might want to sketch it tho ...
