Write the expression sin(tan^-1)x) as an algebraic expression in x (without trig or inverse trig functions).

a. (sqrt (1+x^2))/ (x)
b. (1) / (sqrt (1+x^2))
c. (x) / (sqrt (1-x^2))
d. (x) / (sqrt (1+x^2))
e. (1) / (sqrt (1-x^2))

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
