Trigonometric Identities

· Reciprocal identity of sine and cosecant

Applying the cosecant identity: $\displaystyle\csc\left(\theta\right)=\frac{1}{\sin\left(\theta\right)}$

$\csc\left(x\right)=\frac{1}{\sin\left(x\right)}$
· Pythagorean identity of sine and cosine

Applying the pythagorean identity: $\sin^2\left(\theta\right)+\cos^2\left(\theta\right)=1$

$\sin\left(x\right)^2+\cos\left(x\right)^2=1$
$\tan\left(x\right)+\cot\left(x\right)=\sec\left(x\right)\cdot\csc\left(x\right)$
