Consider the following function. x6 1 + x2 dx (a) Determine an appropriate trigonometric substitution. Use x = sin(θ), where − π
ohaa [14]

Answer:

Step-by-step explanation:

In the first part, we are given the function:

\int \dfrac{x^6}{\sqrt{1+x}^2} \ dx

Suppose we make x = tan θ

Then dx = sec² θ.dθ

= \int \dfrac{tan^6 (\theta)}{\sqrt{1+ tan ^2 \theta }}* dx

= \int \dfrac{tan^6 (\theta)}{\sqrt{1+ tan ^2 \theta }}* sec ^2 (\theta) * d\theta

Since; sec² θ - tan² θ = 1

sec² θ = 1+ tan² θ

sec  \ \theta = \sqrt{1 + tan^2 \  \theta}

∴

= \int \dfrac{tan^6 (\theta)}{sec \  \theta}* sec ^2 (\theta) * d\theta

= \int tan^6 (\theta)* sec (\theta) * d\theta

Thus; In the first part, Use x = tan θ, where  - \dfrac{\pi}{2} < \theta, since the integrand comprise the expression \sqrt{1+x^2}

From the second part by using substitution method;

\int \dfrac{x^6}{\sqrt{1+x^2}} \ dx = \int \mathbf{tan^6(\theta) * sec ( \theta) } \ d \theta

maya wants to mark a length of 7 inches on a sheet of paper, but she does not have a ruler . she has pieces of wood that are 4 i
Vladimir79 [104]
Ok
6+1=7
if only we could find 1
hmm

4+1=5
so mark a starting line
put the 4 inch and 5 inch wood at that line, facing the same direction (lying flat on paper)
the difference between the pieces of wood is 1 inch
mark the end of the 5 inch and the end of the 4 inch
that is 1 inch
now pick either end of that 1 inch mark and measure 6 inches more
