Question

Simplify this trig identity

Answer 1

\[\frac{ \sin(-x) }{ cscx }+\frac{ \cos(-x) }{ secx }\]

Answer 2

i'm stuck at -sinx^2+cos^2

Answer 3

Sinx^2 + cosx^2 = 1

So -1

It's a Pythagorean identity

Answer 4

o

Answer 5

Actually, you could do either -sin^2x=c^2+1
or c^2=1-s^2

Answer 6

for a second i thought it couldn't even be simplified
