\frac{\mathrm{d}}{\mathrm{d}\theta }(\frac{\sin(\theta )}{\cos(\theta )})
Defnyddio diffiniad tangiad.
\frac{\cos(\theta )\frac{\mathrm{d}}{\mathrm{d}\theta }(\sin(\theta ))-\sin(\theta )\frac{\mathrm{d}}{\mathrm{d}\theta }(\cos(\theta ))}{\left(\cos(\theta )\right)^{2}}
Ar gyfer unrhyw ddau ffwythiant y mae modd eu gwahaniaethu, deilliad cyniferydd dau ffwythiant yw’r enwadur wedi’i luosi â deilliad yr enwadur wedi’i dynnu o’r rhifiadur wedi’i luosi â deilliad yr enwadur, y cwbl wedi’i rannu â’r enwadur wedi'i sgwario.
\frac{\cos(\theta )\cos(\theta )-\sin(\theta )\left(-\sin(\theta )\right)}{\left(\cos(\theta )\right)^{2}}
Deilliad sin(\theta ) yw cos(\theta ), a deilliad cos(\theta ) yw −sin(\theta ).
\frac{\left(\cos(\theta )\right)^{2}+\left(\sin(\theta )\right)^{2}}{\left(\cos(\theta )\right)^{2}}
Symleiddio.
\frac{1}{\left(\cos(\theta )\right)^{2}}
Defnyddio'r Hunaniaeth Pythagoreaidd.
\left(\sec(\theta )\right)^{2}
Defnyddio diffiniad secant.
