If i is raised to an even power than I can’t simplify to be <br> i <br> 1 <br> -1
son4ous [18]

Answer:

i

Step-by-step explanation:

i^ even power

i^2 = i*i = -1

i^4 = =1

So raised to an even power, it will be either 1 or negative 1

raised to an odd power it will be either i or -i

Complete the square and give a substitution (not necessarily trigonometric) which could be used to compute the integral. ∫1x2+2x
Ugo [173]

Answer:

Substitution of x+1

Step-by-step explanation:

We are given that

\int \frac{1}{x^2+2x+2}dx

\int\frac{1}{(x^2+2x+1)+1}dx

\int\frac{1}{(x+1)^2+1^2}dx

By using identity

(a+b)^2=a^2+b^2+2ab

Substitute x+1=t

Differentiate w.r.t x

dx=dt

Substitute the values

\int\frac{1}{t^2+1^2}dx

\frac{1}{1}tan^{-1}\frac{t}{1}+C

By using formula :\int\frac{1}{x^2+a^2}dx=\frac{1}{a}tan^{-1}\frac{x}{a}+C

tan^{-1}(x+1)+C
