Half-Angle Identity Formulas $$\cos\frac{\theta}{2}=\pm\sqrt{\frac{\cos\theta+1}{2}}\\ \sin\frac{\theta}{2}=\pm\sqrt{\frac{1-\cos\theta}{2}}\\ \tan\frac{\theta}{2}=\frac{1-\cos\theta}{\sin\theta}=\frac{1+\cos\theta}{\sin\theta} $$ These are the commonly used...
15° is not a commonly known angle, and it doesn't usually appear on the unit circle. But 15 is half of 30, which is a common angle on the unit circle. Use the half-angle identity for sine. sin15∘=1−cos30∘2 1−322 ...

Half-angle formulas extend our vocabulary of the common trig functions. After reviewing some fundamental math ideas, this lesson uses theorems to...
The matched isotopic pattern for each serves as a structural fingerprint for confirming the identity (as observed in the nominal masses of the respective pseudo molecular ions of Ru1-3 when the isotopic distribution of the elements for each complex is considered). These observed mass spectral data...
