Example

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

Question

$$\frac{1+cos\frac{\alpha}{5}-sin\frac{\alpha}{5};}{1-cos\frac{\alpha}{5}-sin\frac{\alpha}{5}}$$

Answer

1+5*l*p*h*a*cos(a)-5*l*p*h*a*sin(a);1-5*l*p*h*a*cos(a)-5*l*p*h*a*sin(a)

Solution


Regroup terms.
\[\begin{aligned}&1+5lpha\cos{a}-(\sin{a})lpha\times 5\\&1-5lpha\cos{a}-(\sin{a})lpha\times 5\end{aligned}\]
Regroup terms.
\[\begin{aligned}&1+5lpha\cos{a}-5lpha\sin{a}\\&1-5lpha\cos{a}-5lpha\sin{a}\end{aligned}\]
