where are the problems
18 problems in all
@n648c788 can you help?
yes I am reviewing some rules
1.) amplitude is heights so it is 2 or -2 dosent matter period is 1/ frequency, so count wavelenghts 1/2=.5
2.) is not periodic
Yes, thank you!
3-5 substact and add the value to 360 3-32+360 -32-360 make sense
What if its negative, then would I add?
- - add numbers - + subtract numbers
Still confused. Could you give an example with end result so I can see the process?
-32+360= 328 -32- 360=-396
Are thos both the answer. Like the answer is two numbers or pick the one thats positive?
its both because it is not specify +, - value wanted
5. 375 is not between 0 and 360
Ok, thanks! I think I got it now!
Theres no answer for number then?
yes good job
How do I do 6 through 8?
6.) conversion degree to radians is angle *2Pi/360 -225*2pi/360= -3.92 radians terms of pie-1.25pi- we just did not multiply pie but we multiplied and divided
7.) 120*2pi/360= 2.09 radians terms of pie= .667pi
8.)600*2pi/360=10.47radians terms of pie= 3.33pi
9-11 we are going backwards
Can you show me an example?
9.) 5pi/6 *180/pi =150 degress 10.) -2.5pi *180/pi= -450 degress 11.) .8*pi/180 = .01396pi .01396pi*180/pi=5 degrees
6-8 do value* pi/360
Okay, thanks! I understand how to do that from now on too!
I dont know about 12
Ok because I can not see the graph
1 cycle, amplitude is 2, period is 1
like when we did number 1
ok next one
y=4sin(2x) 4=amplitude sine period is 2Pi, period formula is 2pi/b, b=2 period=pi now graph
Thats what I g8t too!
14.) y=2sin(4x) Amplitude =2 Period=pi/2 Awseome
I need 15 and 31-33 I have the rest already
15 do you want the points where cos 1/2 is at
No, just the answer in the interval from 0 to 2 pi
x= pi/3, 5pi/3
cos 1/2 is the x value on the unit circle, look at all values where cos is 1/2
For number 15?
our you can look at it this way, first value is pi/3, so we do 2pi-pi/3 and get 5pi/3 because 0-2pi interval
Okay, and numher 31 is just like 13?
32.) remember the conversion
Can you explain 32?
32.) angle *pi/180= radians, #pi*180/pi= degrees
Okay thanks! That helped alot. Just need 33
Ok hold on
33.) 3pi/4= 135degrees 2pi 18*135/360= 42.4inches
Hope you understood everything champ!
Thank you sooo much for all the help and not just giving straight answers but actually taking the time to explain. Fanned and medal! Will write testimonial tonight! :)
And thank you for the enccouraging words!!!
Awesome I appreciate it very much, keep studying hard!
Take care and np!
Could you help me with some more problems? @n648c788
