Mathematics

Ad libitum [116K]3 years ago

Answer:

x = 15

Step-by-step explanation:

We are told that a right angle is divided into two parts

A right angle = 90°

Part A = 30°

Part B = 4x

Hence:

30° + 4x = 90°

Collect like terms

4x = 90° - 30°

4x = 60°

4x = 60/4

x = 15

Therefore, the value of x = 15

Observe that (x^2+2x+2)'=2x+2.

You have that \int \frac{2x}{x^2+2x+2}\; dx=\int \frac{2x+2-2}{x^2+2x+2}\; dx=\int \frac{2x+2}{x^2+2x+2}\; dx+\int \frac{1}{x^2+2x+2}\; dx=I_1+2I_2.

To compute I_1 you set y=x^2+2x+2, so dy=2x+2\; dx. Therefore, I_1=\int \frac{1}{y}\; dy=\ln |y|=\ln |x^2+2x+2|=\ln (x^2+2x+2).

For I_2 observe that x^2+2x+2=(x+1)^2+1. Let y=x+1. Then dy=dx and I_2=\int \frac{1}{y^2+1}=\arctan y=\arctan (x+1).

So, \int \frac{2x}{x^2+2x+2}=\ln (x^2+2x+2)+2\arctan (x+1)+c.
