[DTube] Integral of ∫sin(2x)cos(5x)dx with Product to Sum Formula
In this video, we work through the integral of ∫sin(2x)cos(5x)dx. The first step when performing any integral is to see if we can simplify the integrand, which in this case is: sin(2x)cos(5x) Luckily,

[DTube] Proof the derivative of sin(x) = cos(x) by First Principles
In this video, we prove that the derivative of sin(x) equals cos(x) by the very definition of the derivative, which is: df/dx = f'(x) = lim_(h approaches 0) f(x + h) - f(x) / h Thus: d/dx [sin(x)] = lim_(h

[DTube] Reduction Formula for Integral of ∫ln^n(x)dx
In this video, we work through the derivation of the reduction formula for the integral of lnn(x) or [ln(x)]n. Like with lower powers of ln(x), such as ln2(x), we adopt the same approach of integration

[DTube] Limit of sin(x)/x as x approaches 0: Geometric Proof
In this video, we work through a geometric proof for the limit of sin(x)/x as x approaches 0. You may have visually inspected and tabulated that sin(x)/x does indeed approach L = 1 when x = 0, although
