Answer:

Step-by-step explanation:multiply 3x first with (2x+1)

=6x²+3x

then multiply -2 with (2x+1)

= -4x-2

then add both equations

answer =6x²-x-2

Use a Maclaurin series to obtain the Maclaurin series for the given function.
Rama09 [41]

Answer:

14x cos(\frac{1}{15}x^{2})=14 \sum _{k=0} ^{\infty} \frac{(-1)^{k}x^{4k+1}}{(2k)!15^{2k}}

Step-by-step explanation:

In order to find this Maclaurin series, we can start by using a known Maclaurin series and modify it according to our function. A pretty regular Maclaurin series is the cos series, where:

cos(x)=\sum _{k=0} ^{\infty} \frac{(-1)^{k}x^{2k}}{(2k)!}

So all we need to do is include the additional modifications to the series, for example, the angle of our current function is: \frac{1}{15}x^{2} so for

cos(\frac{1}{15}x^{2})

the modified series will look like this:

cos(\frac{1}{15}x^{2})=\sum _{k=0} ^{\infty} \frac{(-1)^{k}(\frac{1}{15}x^{2})^{2k}}{(2k)!}

So we can use some algebra to simplify the series:

cos(\frac{1}{15}x^{2})=\sum _{k=0} ^{\infty} \frac{(-1)^{k}(\frac{1}{15^{2k}}x^{4k})}{(2k)!}

which can be rewritten like this:

cos(\frac{1}{15}x^{2})=\sum _{k=0} ^{\infty} \frac{(-1)^{k}x^{4k}}{(2k)!15^{2k}}

So finally, we can multiply a 14x to the series so we get:

14xcos(\frac{1}{15}x^{2})=14x\sum _{k=0} ^{\infty} \frac{(-1)^{k}x^{4k}}{(2k)!15^{2k}}

We can input the x into the series by using power rules so we get:

14xcos(\frac{1}{15}x^{2})=14\sum _{k=0} ^{\infty} \frac{(-1)^{k}x^{4k+1}}{(2k)!15^{2k}}

And that will be our answer.

Why do we use variables in math?
Phoenix [80]

Answer:

We use it to substitute an unknown number. We have a variable for a number we don’t know and as we solve the problem we can find the answer for the variable or unknown number.
