X^2=-36 how do I solve this

OLEGan [10]

Hey!

---------------------------

Answer:

No Real Solutions.

---------------------------

Explanation:

Well, because you would typically find the square root of -36 but there is no real solution that would equal -36. If it was x^2 = 36 it would be a totally different thing.

Hope This Helped! Good Luck!

Evaluate this integral. I'm not sure how to evaluate integrals with absolute values.

SOVA2 [1]

Answer:

Step-by-step explanation:

The first step is to understand what the integrand looks like. (See the graph below.)

It is -1 for x < 0 and +1 for x > 0. Thus, the value of this integral is ...

$\int\limits^0_{-1} {-1} \, dx + \int\limits^2_0 {1} \, dx=-1+2=1$

_____

Essentially, you treat the absolute value as a piecewise linear function. This is the same way you treat an absolute value in any equation or inequality.

Here, this means you divide the integral into two parts: one where the integrand is -x/x, and one where it is +x/x.
