 Exercise

 

Math interpretation of the question

$\sin\left(30\right)\cos\left(30\right)\cot\left(60\right)$

 

Simplify $\sin\left(30\right)\cos\left(30\right)\cot\left(60\right)$ using the trigonometric identity: $\sin(2x)=2\sin(x)\cos(x)$

$\frac{\sin\left(2\cdot 30\right)}{2}\cot\left(60\right)$

 

Multiply $2$ times $30$

$\frac{\sin\left(60\right)}{2}\cot\left(60\right)$

 

Multiplying the fraction by $\cot\left(60\right)$

$\frac{\sin\left(60\right)\cot\left(60\right)}{2}$

$\frac{\sin\left(60\right)\cot\left(60\right)}{2}$
