Integral from 0 to 1 of (x^2)(e^x^3)

you need u-substitution. let u=x^3 therefore, du= 3x^2 dx. replace the x^3 in e^x^3 with u, so its e^u. x^2 is replaced with du, but since there is a factor of 3 missing, you balance it out by bringin

Calculus 2: Find the angle difference (in radians) between adjacent 4th roots.

Let z = e^(2π i /n). Then z^n = 1, and z is called an nth root of unity. There are n nth roots of unity, equispaced around the unit circle; they have the form z = e^(2π i (k/n)), where k = 0, 1, 2,, n
