prove the statment using the epilson, delta defintion of limit:
lim x^2+x-6/x-2=5
x→ 2
how do i go about solving this?
ok thanks a lot
one other question, would I have to convert the answer to feet?
these for the values I got for t using the quadratic formula:
t=0, and t is approx. 18.07
then i plugged 18.07 into the first equation and got:
approx. 1124.41
this is right? is this the answer?oh yeah, what units would i use?
7.) If an object is thrown on the moon, then the parametric equations of flight are:
x=(vcostheta)t and y=(vsintheta)t-2.66t^2+h.
Estimate the distance that a golf ball hit at 88 ft. per sec (60 mph) at an angle of 45 degrees with horizontal travels on the moon if the moon's surface is level.
how would i go about sloving this?where would i start?
thank you so much
I have no idea how to finish this problem I am stuck on this step:
P=0.01(sin(443pit)cos(-3pit))
how do i finish this?when i graph it on the calculator i get nothing
so if i decide to plug in .44 as x i should get one single value right?
then using the order pair plot the dot?
ok so its:
0.005[sin(440pit)+sin(446pit)]=2sin(440+446/2)cos(440-446/2)?
then after this i get all terms to one side right? then graph?
Consider two tones with frequencies of 220 and 223 Hz and pressures P1=.005sin440(pie)t and P2=.005sin446(pie)t, respectively. Graph the pressure P= P1+P2 felt by an eardrum over the 1-sec interval [.15,1.15]. How many beats are there in 1 sec?
my work:
am I goin about this right?
P=.005sin(440pit)+.005sin(446pit)
P=.01sin(886pit)
now is this ready to graph in the interval [.15,1.15]?
or is there another step i need to do?
ok thanks a lot just needed clarification.
ok so this is what i am getting form you:
(in degrees)
arcsin(1/1.2)=56.44269024
now from here can i just go ahead and multiply the 2 or do I have to do something else first?
this is where i am confused
i confused why do u keep stating add or subtract 360 or 2pi any number of times
i was following the formula in the book and your answer is very similar to the format they used. This is what I got for my final answer:
3sqrt(u^2+1)/(u+1)
Basically i am stuck:
1.) cos(arctan(3/u))
my work:
theta=arctan(3/u)
tan(theta)=3/u
now what do i do?
2.) theta=2arcsin(1/1.2)
my work:
divided 1.2 into 1 and got:
theta= 2(.9851107833)
then do i multiply 2 into .9851107833?
am i doing this right?
