A number is said to be an Armstrong number if the sum of the cubes of all
of its digits equals its value. Write a pseudo-code that given number N tells if it is
Armstrong or not. For example 153 is an Armstrong number: 13 + 53 + 33 = 153

g(x, y) = 2*x*y + y^4 @ (1, 1) in the direction u = (4, -3)

and also the directional derivative of g(x, y) = x^2 - 2*x*y^2 @ (2,1) along a line which makes an angle of (pi/3) to the + x axis.

Thanks in advance.

f(x)=t^4-5t

i don't think the h->0 approach will work seeing as how expanding (a+h)^4 is really hard, and i think it gets worse even after you factor.

do i use the x->a method? if so how do i go about this?

y= -2/3x +4 by graphing 3 points.

y= x - 3 by graphing 3 points.

3x - 2y = 6 by graphing the x and y intercepts.

-x + 3y = -9 by graphing the x and y intercepts.

4x - 3y = 6 by the slope intercept method.

3x + 5y = 12 by the slope intercept method.
