knowing that: cos(x)=Σ_(n=1) ^∞ (((−1)^n x^(2n) )/((2n)!)) sin(x)=Σ_(n=1) ^∞ (((−1)^n x^(2n+1) )/((2n +1)!)) prof that: cos(x+y)= cos(x)cos(y)−sin(x)sin(y)

$k n o w i n g t h a t :$ $c o s (x) = \underset{n = 1}{\sum^{\infty}} \frac{{(- 1)}^{n} x^{2 n}}{(2 n)!}$ $s i n (x) = \underset{n = 1}{\sum^{\infty}} \frac{{(- 1)}^{n} x^{2 n + 1}}{(2 n + 1)!}$ $p r o f t h a t : c o s (x + y) = c o s (x) c o s (y) - s i n (x) s i n (y)$

if log(a+b+c)=loga+logb+logc prove log(((2a)/(1−a^2 ))+((2b)/(1−b^2 ))+((2c)/(1−c^2 )))=log(((2a)/(1−a^2 )))+log(((2b)/(1−b^2 )))+log(((2c)/(1−c^2 )))

$i f l o g (a + b + c) = l o g a + l o g b + l o g c$ $p r o v e$ $l o g (\frac{2 a}{1 - a^{2}} + \frac{2 b}{1 - b^{2}} + \frac{2 c}{1 - c^{2}}) = l o g (\frac{2 a}{1 - a^{2}}) + l o g (\frac{2 b}{1 - b^{2}}) + l o g (\frac{2 c}{1 - c^{2}})$
