What is the four digit number in which the first digit is 1 quater of the last digit, the second digit is 6 times the first digit, and the third digit is the second digit plus three?
If anyone solves this I will be highly impressed. (Show work plz).
So Intregal of Sin x squared?
Well you have to change the sin(x^2) to it's double angle side.
The doubled angle side of sin(x^2) is 1-Cos(x2). Then because of the intregal, We do 1/2. So this is now 1/2 1-cos(x2).

Am I close?
It's not sin²(x), it's sin(x²). The x is squared, not the sine function so identities don't work.
