Simpler cases with n equal to 1, 0 or -1 are summarized in the table on the right. tan x = n General case An equation of the form tanx = n has solutions for any real n. To find them we must first find an angle α such that: After finding α, the solutions for x are: When n equals 1, 0 or -1 the solutions have simpler forms which are shown in the table on the right. cot x = n General case The equation cotx = n has solutions for any real n. To find them we must first find an angle α such that: After finding α, the solutions for x are: When n equals 1, 0 or -1 the solutions have simpler forms which are shown in the table on the right.

71828183 To calculate cos(θ), we would apply the formula: 2*cos(θ) = = + = => cos(θ) = e(iθ)+e(-iθ) 1 + iθ - θ**2/2 - iθ**3/6 + θ**4/24 + ... 1 +-iθ - θ**2/2 --iθ**3/6 + θ**4/24 + ... 2 -2θ**2/2 +2θ**4/24 + ... 1 - θ**2/2 + θ**4/24 + ... )+ ... in which the odd terms cancel out and the even terms double and alternate in sign. Substituting -θ for θ does not change the result as θ occurs with even powers, hence the earlier phrase that cos() is an even function. Using the Taylor series to calculate π Having calculated, e and cos(), lets see if we can calculate π.

To summarize what we know so far: cos(θ) = e(iθ)/2 + e(-iθ)/2 where θ is in radians and i is a square root of -1. Replacing θ by -θ gives conversly: cos(-θ) = e(-iθ)/2 + e(iθ)/2, the same formula, so we must have that cos(θ) = cos(-θ). Given: cos(θ) = e(iθ)/2 + e(-iθ)/2 We can find the rate of change with θ of both sides to fined the sin() in terms of e() => -sin(θ) sin(θ) = = i+e( iθ)/2 - i*e(-iθ)/2 i*e(-iθ)/2 - i*e( iθ)/2 Substituting -θ for θ gives: sin(-θ) = i*e(iθ)/2 - i*e(-iθ)/2 = -sin(θ) thus sin() is an odd function, compare this to cos() which is an even function because cos(θ) = cos(-θ).
