If X = a^1/3 - a^-1/3 , show that x^3 + 3x = a - 1/a

ICE Princess25 [194]

Answer:

Step-by-step explanation:

Hello,

$(a^{1/3}-a^{-1/3})^3=a-3a^{1/3}+3a^{-1/3}-\dfrac{1}{a}=-3x+a-\dfrac{1}{a}\\\\ x^3+3x=a-\dfrac{1}{a}$

Thanks

Rotate the yellow dot to a location of pie radians. After you rotate the angle, determinethe value of cos(pie). to the nearest h

Len [333]

Okay, here we have this:

Considering the provided angle, we are going to calculate the requested cosine, so we obtain the following:

Then to obtain the cosine we will review the following image of the unit triangle:

So since pi radians is equal to 180°, we can see in the image that the cosine of 180 degrees is equal to -1, so we finally get that the cosine of the angle is -1.
