Given: 2sin^2 x - 1 = 0
2sin^2 x = 1
sin^2 x = 1/2
sin x = ±1/sqrt(2)
x = 45° or 135° (or n/4, 3 n/4)
Answer: x = n/4, 3n /4 (mod 2n )

Evaluate ∫01 xex² dx.

Weegy: The value of the integral is (e − 1)/2. Sol'n: Let u = x², du = 2x dx → x dx = du/2 ∫ xex² dx = (1/2) ∫ eu du = (1/2)eu + C = (1/2)ex² + C Evaluate from 0 to 1: (1/2)e1 − (1/2)e0 = (e − 1)/2 (More)

Given: dy/dx=y^2, y(0)=1
Separate: dy/y^2=dx
y^-2 dy = dx
-1/y = x + C
At x=0,y=1: -1= C
So -1/y = x-1
1/y = 1-x
y = 1/(1-x)
Answer: y=1/(1-x)
