Simplify the trigonometric expression sin x sec x.

Given that sec x = ​ (a)   and tan x = ​ (b)   , the simplified expression is ​ (c)  

• tan x

(cot²x) / (cscx+1)

• cscx +1

• cscx−1

• secx−1

• secx+1

sinx(cotx+tanx)

• cosx

• cscx+1

• cosx-2

• secx

tan(x)/sec(x)

• cos(x)

• does not simplify

• sin(x)

• tan(x)

tan(x)csc(x) 

• tanx

• secx

• cotx

• cscx

(sec²x)(1 - sin²x)

• -cos(x)

• 1

• -1

• -sin(x)
