Just someone who loves maths.

 8 How should I approach taking math tests? 6 Proof that $\sum\limits_{k=1}^nk^2 = \frac{n(n+1)(2n+1)}{6}$? 5 Proof by induction that $2^n \gt n^k$ 3 Trigonometry: Solve $(1-\cos\alpha)^2 + \sin^2\alpha = d^2$ for $\alpha$ 1 How does $\sum_{n = 1}^{\infty} \frac{1}{n(n+1)}$ simplify?
