lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

\frac{1+Cos2x}{Sin2x}

We have to verify the identity.

We know that

1+Cos2x=2Cos^2 x

Sin2x=2SinxCos x

Using the formula

\frac{2Cos^2x}{2SinxCosx}

\frac{Cosx}{Sinx}

Cot x

By using the formula

Cotx=\frac{Cosx}{Sinx}

LHS=RHS

Hence, verified

Why is -7 an integer but not a natural number?
MrMuchimi

Answer:

Natural Numbers are basically "counting numbers". If I ask you to start counting, you'll start at 1, then 2, then 3, and so on. It doesn't include 0 or any negative numbers because you wouldn't start from -10 when asked to count.

KIM [24]

The correct answer is C.


You can tell this by factoring the equation to get the zeros. To start, pull out the greatest common factor.


f(x) = x^4 + x^3 - 2x^2


Since each term has at least x^2, we can factor it out.


f(x) = x^2(x^2 + x - 2)


Now we can factor the inside by looking for factors of the constant, which is 2, that add up to the coefficient of x. 2 and -1 both add up to 1 and multiply to -2. So, we place these two numbers in parenthesis with an x.


f(x) = x^2(x + 2)(x - 1)


Now we can also separate the x^2 into 2 x's.


f(x) = (x)(x)(x + 2)(x - 1)


To find the zeros, we need to set them all equal to 0


x = 0


x = 0


x + 2 = 0

x = -2


x - 1 = 0

x = 1


Since there are two 0's, we know the graph just touches there. Since there are 1 of the other two numbers, we know that it crosses there.
