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

that being opposite over hypotenuse
and by the same triangle

cos(tan−1(x)) = x / (square root (1 + x^2))

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
