Step-by-step explanation:

the formula is :

tan (a+b) =

(tan (a) + tan (b)) / ( 1 - tan (a) . tan (b))

therefore

tan (π/5) + tan (π/2)) / (1-tan (π/5) tan (π/2))

= tan (π/5 + π/2)

skelet666 [1.2K]

Step-by-step explanation:

f°g=f(g(x))

g(x)=x^2-6x

f(x)=1/x

f(g(x))=\frac{1}{x^2-6x}

if the denominator is zero the number is undefined which makes it not in the domain of the function

set x^2-6x equal to 0

the values for x is 0 or 6

so the only value that is not in the domain of f°g is 0 and 6

Hope that helps :)
