It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios (sine, cosine, tangent, cotangent, secant and cosecant).

Let x ∈ I where I is at most the open interval (0, π / 2) (because tan ⁡ x > 0) must be true. Then tan ⁡ x → 1 as x → π / 4, so log ⁡ tan ⁡ x → 0. Also, sin ⁡ x − cos ⁡ x → 0 as x → π / 4. Together, this means the numerator and denominator both converge to zero in the limit, yielding a case of L’Hôpital’s rule.
