Tan 2A + sin 2A=4 tan A/(1 - tan4 A)​
stich3 [128]

Answer:

when \:  \\  \tan(2x)  =   \frac{2 \tan(x) }{1 -  {( \tan(x)) }^{2} }  \:  \: and \\  \sin(2x)  =  \frac{2 \tan(x) }{1 +  {( \tan(x)) }^{2} }  \\ then \\  \sin(2x)  +  \tan(2x)  =  \frac{2 \tan(x) }{1 -  {( \tan(x)) }^{2} }  +  \frac{2 \tan(x) }{1 +  {( \tan(x)) }^{2} }  \\  =  \frac{2 \tan(x)(1 +  {( \tan(x)) }^{2}  + 2 \tan(x) (1 -  {( \tan(x)) }^{2}  }{(1 +  {( \ \tan(x))  }^{2}(1 -  {( \tan(x)) }^{2}  }  \\  =  \frac{2 \tan(x) \times 2 }{1 -  {( \tan(x) }^{4} }  \\  =  \frac{4 \tan(x) }{1 -  {( \tan( \times ) )}^{4} }

suppose that G(x)=F(x+2) which statement best compares the graph of G(x) with the graph of F(x) A. the graph of G(x) is the grap
vampirchik [111]

Answer:

Last option is the correct answer:

The  graph of G (x) is the graph of f(x) shifted 2 units to the left

Step-by-step explanation:

We know that for any parent function f(x) the graph of the transformed function:

g(x)=f(x+a)

is a shift of the the parent function f(x) either to the left or the right depending on the value of a.

if a>0 then the shift is 'a' units to the left

and if a<0 then the shift is 'a' units to the right.

Here we have transformed function G(x) as:

G(x)=F(x+2)

i.e. a=2>0.

Hence, the  graph of G (x) is the graph of f(x) shifted 2 units to the left.
