Summary
| Description |
English: graphic showing the derivation of sin(x). curve(DC)=delta, DE=DC.cos(phi), phi=ceta+delta-delta/2, [d/d(ceta) sin(ceta)] = lim(delta->0)(DE/curve(DC)) = lim(delta->0)(DE/DC)*lim(delta->0)(DC/curve(DC)) = lim(delta->0)(cos(phi))*1 = lim(delta->0)(cos(ceta+delta/2)) = cos(ceta) |
