If any number to the zero power is 1... the does that make 31 to the zero power 1 or 31?

1 answer:

5 0

31 to the zero power is 1, anything but zero to the power of zero is 1. Zero to the power of zero is undefined. Hope that helps

A student solved the equation sin2x/cosx=2, 0<=x<=pi and found the answer of pi/2 describe the students error

finlep [7]

For the given equation ⇒⇒⇒ $\frac{sin \ 2x}{cos \ x} =2$
and the given range 0 ≤ x ≤ π
We should note that the zeros of the denominator will be at
cos x = 0
∴ $x = cos^{-1} 0 = \frac{\pi}{2}$
So, the given equation is undefined at π/2
So, <span>the students error is the division by zero.

See the attached figure which represents the graph of the given equation and we can see it is undefined at π/2
