Question

Rewrite the expression in terms of the given function or functions. (sec x + csc x) (sin x + cos x) - 2 - cot x; tan x
A. 0
B. 2tan x
C. tan x
D. 2 + tan x

Answer 1

well rewrite the brackets and simply that 1st


(1cos(x)+1sin(x))×(sin(x)+cos(x))


sin(x)cos(x)+1+1+cos(x)sin(x)


simplifies to
tan(x)+cot(x)+2


so the equation becomes

tan(x)+cot(x)+2−2−cot(x)=tan(x)
