How to solve: Sin(x)=x^2-pi^2

Mathematics
1 answer:
LiRa [457]3 years ago
6 0

Rewrite the equation as

\sin(x) = x^2-\pi^2 = (x-\pi)(x+\pi)

If we choose x=\pm\pi, the right hand side becomes zero, and so does the left hand side.

If you graph the two functions f(x) = \sin(x) and g(x) = x^2-\pi^2, you'll see that there are only two solutions, so the ones we found are the only ones.

Two sides of a triangle have lengths 11 and 18. Write an inequality to represent the possible lengths for the third side, x.
KatRina [158]
<span>Side inequality of triangle states that the sum of any two sides of a triangle should be greater than the third side so the sum of two sides

In this case, 11 + 18 = 29 > 3rd side So 29 > 3rd side or we can say 3rd side < 29

Also, the third side cannot be smaller than the difference of the given two sides so the third side has to be greater than 18-11 = 7 so 3rd side > 7 so if length of 3rd side is represented by x, then 7 < x < 29</span>
