Question

Verify the identity. Justify each step.

Answer 1

well you know that tanx = sinx/cosx and cotx = cosx/sinx

Answer 2

add
\[\frac{b}{a}+\frac{a}{b}\]

Answer 3

\[\frac{sinx}{cosx} +\frac{cosx}{sinx} \] then simplify it

Answer 4

how do i simplify that?

Answer 5

\[\frac{sinx*sinx}{cosx*sinx} +\frac{cosx*cosx}{sinx*cosx} \]
and Note the fact that;; sin^2+cos^2x = 1

Answer 6

so the answer is 1?

Answer 7

why not try it first; simplify it

ithe answer cannot be 1
