root(125^x) = 125^(x/2) = 5^(3x/2)
5^(3x/2) / 5^(2x-1) = 5^(3x/2 - 2x +1) = 5^(-x/2 + 1)

Pi radians is equal to 180 degrees . Radians are a unit of measurement for angles, just like degrees are, and pi is just the number of radians that makes up that angle. 180 divided by 3 is 60 so we get c...

If the projectile is released at an angle, it will have 2 components: 1. horizontal component of motion and 2. vertical component Horizontally, the projectile is assumed to travel at a constant speed (ie ...

The unsimplified form of the derivative can be obtained fairly easily with use of the quotient rule. The trick for simplification is to multiply top and bottom by (x+4)^0.5, this allows manipulation of th...

Firstly, integrate each term individually, starting off with the 3x^4. In order to integrate the index on the x term needs to be raised by 1, and the coefficient of the x should be divided by this new val...
