kondaur [170]

Answer:

\int \dfrac{du}{u}=\log|u|+C

\int u^n du=\dfrac{u^{n+1}}{n+1}+C

\int \dfrac{du}{u\sqrt{u^2-a^2}}=\dfrac{1}{a}\csc^{-1}(\dfrac{x}{a})+C

Step-by-step explanation:

a.

\int \dfrac{du}{u}=\log|u|+C    [\because \int \dfrac{dx}{x}=\log |x|+C]

b.

\int u^n du=\dfrac{u^{n+1}}{n+1}+C    [\because \int x^n dx=\dfrac{x^{n+1}}{n+1}+C]

c.

\int \dfrac{du}{u\sqrt{u^2-a^2}}=\dfrac{1}{a}\csc^{-1}(\dfrac{x}{a})+C        [\because \dfrac{adx}{x\sqrt{x^2-a^2}}=\csc^{-1}(\dfrac{x}{a})+C]

Given point B is located at
ELEN [110]

Answer: \Large\boxed{Point~B'~=~(-4,~-2)}

Step-by-step explanation:

<u>Given information</u>

Point B = (-2, -4)

Reflection line: y = x

<u>Concept:</u>

When reflecting over the line y = x, the position of y and x in the original coordinate switches places.

This is because it is " y = x ", assuming that they could interchange

<u>Find the coordinate of Point B'</u>

Original (x, y) = (-2, -4)

Point B' = (x', y') = (y, x) = \Large\boxed{(-4,~-2)}

<em>Please refer to the attachment below for a graphical understanding</em>

Hope this helps!! :)
