Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\sin\ 30^{\circ}(\cos\ 30^{\circ}+\sin\ 60^{\circ})$$

Answer

e*g*sin(30*d)*(e*g*cos(30*d)+e*g*sin(60*d))

Solution


Regroup terms.
\[(\sin{30d})eg(eg\cos{30d}+(\sin{60d})eg)\]
Regroup terms.
\[(\sin{30d})eg(eg\cos{30d}+eg\sin{60d})\]
Regroup terms.
\[eg\sin{30d}(eg\cos{30d}+eg\sin{60d})\]
