Given that the antiderivative of f of x equals 1 divided by the quantity x squared plus 1 is F(x) = tan-1(x) + C, evaluate the i
andreyandreev [35.5K]

Answer:

You know that if f(x) = 1/(x²+1) then F(x)=arctan(x).

What is arctan(x) function? It is inverse function of tan(x) in tge range (-π/2, π/2).

So if tan(x) = y then x = arctan(y)

therefore arctan(-1) = -π/4 because tan(-π/4)=-1 and arctan(1)=π/4 because tan(π/4) = 1.

In conclusion:

integral (dx/(x²+1)) from -1 to 1 =

= F(1) - F(-1) = arctan(1) - arctan(-1) =

=π/4-(-π/4)=π/4+π/4 = π/2.

answer B is correct

Mason wrote the expression shown below 5(y+2). Write an expression that is equivalent to Mason’s expression
rusak2 [61]

Answer:

5y+10

Step-by-step explanation:

The best way to rewrite this equation is to use the distributive property.

5y+10

Or, we can just use the commutative property to switch the numbers around, but I recommend the distributive.

5(2+y)

Hope this helps!
