in trigonometry identities
write each expression in terms of sin x only.
1.tan x cos x
2. cot x cos x
3.cot x/ cos x
4. csc x/ sin x
5. tan x/ cos x


Sagot :

I hope these identities will help you.
[tex]tanx= \frac{sinx}{cosx} [/tex]
[tex]cotx= \frac{cosx}{sinx} [/tex]
[tex]cscx= \frac{1}{sinx} [/tex]
[tex]sin^2x+cos^2x=1[/tex]

Just use those identities with your given questions and you're ready to go. :)

I'll give a few answers.
1. sinx, since [tex] \frac{sinx}{cosx} cosx=sinx[/tex]
2. [tex] \frac{cosx}{sinx} cosx=cos^{2}x/sinx=\frac{1-sin^{2}x}{sinx}[/tex]
