Question

what is the identity of sin x sec x?

Answer 1

\(\bf sin(x)sec(x)\implies sin(x)\cdot {\color{brown}{ \cfrac{1}{cos(x)} }}\implies ?\)

Answer 2

recall that \(\bf sin(\theta)=\cfrac{1}{csc(\theta)}
\qquad

% cosine
cos(\theta)=\cfrac{1}{sec(\theta)}
\qquad

% tangent
tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}\)

Answer 3

well and \(\bf sec(\theta)=\cfrac{1}{cos(\theta)}\)

should be pretty obvious there though
