AP CALC QUESTION!! WILL MARK BRAINLIEST (TWO QUESTIONS)
kodGreya [7K]

1. Using washers, the volume is given by the integral

\displaystyle\pi\int_1^{e^2}((2+2)^2-(\ln x+2)^2)\,\mathrm dx

=\boxed{\displaystyle\pi\int_1^{e^2}(20+4\ln x-(\ln x)^2)\,\mathrm dx}

We're using washers whose centers depend on the value of x, hence we integrate with respect to

2. The area of the given region is given by the integral

\displaystyle\int_0^2\sin^{-1}\frac x2\,\mathrm dx

To compute the integral, first consider the substitution u=\frac x2, or 2u=x so that 2\,\mathrm du=\mathrm dx. Then x\to0\implies u\to0 and x\to2\implies u\to1, so the integral is equivalently

\displaystyle2\int_0^1\sin^{-1}u\,\mathrm du

Integrate by parts, taking

f=\sin^{-1}u\implies\mathrm df=\dfrac{\mathrm du}{\sqrt{1-u^2}}

\mathrm dg=\mathrm du\implies g=u

so that

\displaystyle2\int_0^1\sin^{-1}u\,\mathrm du=2\left(u\sin^{-1}u\bigg|_0^1-\int_0^1\frac u{\sqrt{1-u^2}}\,\mathrm du\right)

\sin^{-1}0=0 and \sin^{-1}1=\frac\pi2, so the area is

\displaystyle\pi-2\int_0^1\frac u{\sqrt{1-u^2}}\,\mathrm du

For the remaining integral, substitute w=1-u^2, so that \mathrm dw=-2u\,\mathrm du. Then u\to0\implies w\to1 and u\to1\implies w\to0:

\displaystyle\pi-\int_0^1\frac{\mathrm dw}{\sqrt w}

(notice that the integral is improper)

\displaystyle\pi-\lim_{t\to0^+}2\sqrt w\bigg|_t^1

\displaystyle\pi-2\left(1-\lim_{t\to0^+}\sqrt t\right)=\boxed{\pi-2}

The concepts of natural selection and evolution are central to how most biologists
Pavlova-9 [17]

Answer:

For many people of different religious beliefs, the theory of evolution does not pose a conflict. However, Christian fundamentalists, in particular, may portray evolution and religion as in opposition to each other. Some people think that, to accept the key tenets of evolutionary thought is to deny their religious beliefs, and this prospect can generate considerable conflict. This is not helped by some proponents of evolution, who make derogatory statements about religious beliefs and promote evolution as explaining all there is to know about life. It is important to understand that western science developed within the Church and Philosophers traditionally explained the wonders of natural life through a creator. However, our knowledge and understanding of the natural world, developed through the application of the scientific method, has provided us with a modern and testable explanation for the history and relationships of living things.

This writing team takes the position that there is no conflict between Religion and Evolution because they are two incompatible areas that have nothing to do with each other. We do, however, understand that this is not necessarily the opinion of all. We have, for that reason, prepared the following section to spark critical discussion and reflection on some of the issues.

Darwin and Evolution

Why were Darwin's findings so controversial, and why do they still pose a challenge to some people's religious beliefs.

Specialists' panel

We have documented a number of previously published statements from specialists, stating why the acceptance of evolution poses no threat to their faith, or to them teaching evolution at school.

Roundtable discussion

For the roundtable discussion we have asked scientists a set of questions to which they have replied. These could be used as a starting point for discussion and critical thought.

Darwin and Evolution

Darwin's book, "The Origin of Species" belongs to the category of scientific work that is much discussed but is often not actually read. His findings are amongst the most significant and important that have ever been produced by scientists.
