Question

if f(x) = sec x and g(x)= sin x , which statement is true,
a) (f×g)(x)= cosx
b) (f×g)(x)= cotx
c) (f×g)(x)= cscx
d) (f×g)(x)= tanx

Answer 1

\[(f×g)(x)=f(x)g(x)=\]

Answer 2

simplify using \[\sec=\frac1\cos\]

Answer 3

OH WAIT.... got it ..

Answer 4

sec x = 1/cosx

1/cosx (sinx) = sinx/cosx = tan x
