Regardless of what 'x' is, (x)0 = 1 .
tan(1 radian) = 1.55741 (rounded)
tan(1 degree) = 0.01745 (rounded)
We can't remember the derivative of the tangent right now, but it doesn't matter.
This particular tangent is a constant, so its derivative is zero.

x0 = 1 because any number raised to the power of 0 is always equal to 1
1 anything to the power of 0 equals 1 100=1 x0=1
That would besqrt[ (x80 - x0)2 + (y80 - y0)2 ) at an angle of tan-1 (y80 - y0) / (x80 - x0)or(x80 - x0) i + (y80 - y0) j
Any number to the power zero is equal to one. That can be derived from the following index law: xa*xb = xa+b (x not zero) Now let b = 0 so that the above becomes xa*x0 = xa+0 so xa*x0 = xa (since a+0 = a) That is, any number multiplied by x0 is the number itself. That can be true only if x0 is the multiplicative identity, that is, only if x0 = 1.
