sin(x) lim = 1 x→0 x In order to compute speciﬁc formulas for the derivatives of sin(x) and cos(x), we needed to understand the behavior of sin(x)/x near x = 0 (property B). In his lecture, Professor Jerison uses the deﬁnition of sin(θ) as the y-coordinate of a point on the unit circle to prove that lim θ→0(sin(θ)/θ) = 1.

So the challenge is to find upper and lower bounds for x sinx. Consider: We have: {Area of Δ KOA} ≤ {Area of Sector KOA} ≤ {Area of Δ LOA} ∴ sinx 2 ≤ x 2 ≤ tanx 2. Multiplying by 2 sinx gives: 1 ≤ x sinx ≤ 1 cosx. ∴ lim x→0 1 ≤ lim x→0 x sinx ≤ lim x→0 1 cosx. ∴ 1 ≤ lim x→0 x sinx ≤ 1.
