so what should I do if the the given cannot be factored by synthetic division? I already encountered one in differential equations and I do not know what to do.
Homework Statement
Can someone tell what are the other factoring methods when dealing with equations higher than the second degree. The only I is the synthetic division. Aside from that, I do not know anything. I need other factoring methods so I can deal with problems that cannot be...
Homework Statement
f(x) = 1 0<t<1
= -1 1<t<2
How can I simplify this given that function(on the attachment).
What I mean is that how can I write the function in any other way?
In addition, How can I know if the function can be written in other form?
How can I...

I asking how I get that
I do not know what should I do
thats what i am saying. f(t+2) =f(t) is given. what im trying to prove is that if k is not equal to zero, the period f is 2.
how i should i plot the 1+kt?
Homework Statement
The elements of f(t) are 1+kt and t here are 0<t<1
the other element is 1 and t here are 1<t<2.
f(t+2)=f(t)
prove if k is not equal to zero, the period f is 2.
i know the graph of element 1 but how should I graph the other element with k.
Based from the graph...
without using the listing of multiples, will this work?
lets say, find the LCM of pi/2 and 3pi/4
Using LCD pi/2 becomes 2pi/4 and 3pi/4 is still 3pi/4
By multiplying 2 and 3, it becomes 6
Then the LCM is 6pi/4 or 3pi/2
Im talking about his last post, pi/2 and 3pi/2, how it became 3pi/2. All I know about LCM is it for whole number just like the LCM of 3,5,and 15 is 30. For fraction, it is LCD.
how about if the function comes in many terms?
for example: 1+cost+cos2t
Will I get the larger period among them or use the LCM?
if LCM, how do I do that?
Homework Statement
The function is defined on (-infinity, +infinity)
Find the fundamental period of sin(5t+\pi)
Homework Equations
The Attempt at a Solution
f(x)=sin(5t+\pi)
f(x)=f(x+2p)
f(x+2p)=sin(5t+\pi+2p)
f(x+2\pi/5)=sin(5t+\pi+2\pi/5)
The period i got was...
