Find the exact value of: {eq}\sin(135 ^\circ) {/eq}.Relationship Between Sine and CosineOne notable relationship between the sine and cosine functions is that, suppose we have {eq}\cos(\theta) {/eq}, a phase shift of {eq}90^{\circ} {/eq} of the angle {eq}\theta {/eq} woul...
This gives us the following value of sin 3°: or other forms depending how you factor the above. sin 6°:Using the above, one can compute the sine of 6 degrees finally as sine of twice 3 degrees to arrive at sin 18° and sin 72°:Taking the equivalent sine and cosine values of 15...

This paper re-evaluates the formative year of quantum mechanics—from Heisenberg’s first paper on matrix mechanics to Schrödinger’s equivalence proof—by focusing on the role of radiation in the emerging theory. We argue that the radiation problem played a key role in early quantum mechanics,...
