It seems like your question is incomplete. If you meant to verify a mathematical statement or expression involving "-x," please provide the full context or equation you're referring to, and I'll be happy to help!
(3pi-7)/9 To verify this go to the link and enter integrate x cos(x)^3 from 0 to pi/2.

60x=50 -> x=50/60 -> x=5/6 Verify: 60x=50 -> 60 x 5/6=50 -> 50=50 Hence Verified.
Let us assume that original number as x x * (33.3/100) = 27 x * 33.3 = 2700 x = 2700 / 33.3 = 81.081 Verify Answer: 81.081 * 0.333 = 26.999973
According to Wolfram Alpha, input:integral csc x it is -log[cot(x) + csc(x)] + constant You can verify this by taking the derivative of the purported integral.
The anti-derivative of any constant c, is just c*x. Thus, the antiderivative of pi is pi*x. We can verify this by taking the derivative of pi*x, which gives us pi.
(sin(x)cot(x) - cos(x))/tan(x)(Multiply by tan(x)/tan(x))sin(x) - cos(x)tan(x)(tan(x) = sin(x)/cos(x))sinx - cos(x)(sin(x)/cos(x))(cos(x) cancels out)sin(x) - sin(x)0
x multiplied by x is x squared.
Sample Answer: To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove equivalence.
The (unknown) x (I suppose that's what you mean) is a variable. It's commonly used to represent any number. For example if you have the equation 3x+2=5, x represents the number which will verify the equation. x can be used with equations, functions etc.
cot x = (cos x) / (sin x) cos (x - 180) = cos x cos 180 + sin x sin 180 = - cos x sin (x - 180) = sin x cos 180 - cos x sin 180 = - sin x cot (x - 180) = (cos (x - 180)) / (sin (x - 180)) = (- cos x) / (- sin x) = (cos x) / (sin x) = cot x
