  (3) x – x3/3 + x5/5 – x7/7 + … = arctan x. by antidifferentiating. (Check: If we differentiate the left hand side of (3) term-by-term, we get the left hand side of (2). Likewise if we differentiate arctan x, we get 1/(1+x2). So the LHS and RHS of (3) have the same derivative.) Now substituting x = 1 into (3) we get

  You have the series for the derivative of arctan(x). This shows the true power of Taylor series: the easy manipulation of functions. Polynomials are far easier to manipulate than, say, arctan(x), and now we have a way to manipulate them.

  Find the exact value of sin, cos or tan of an angle that is the sum or difference of 2 angles on the unit circle or half an angle on the unit circle. For example evaluate sin(13π/12) or tan(17π/12), cos(π/8) etc. You may need to find the angles yourself! You will likely be required to simplify expressions completely.
