tanx + cotx =![\frac{1}{sinxcosx}](/tpl/images/1008/1447/1daa6.png)
Step-by-step explanation:
Explanation
Take R.H.S =![\frac{1}{sinxcosx}](/tpl/images/1008/1447/1daa6.png)
=![\frac{sin^{2}x+cos^{2}x }{sinxcosx}](/tpl/images/1008/1447/87ab0.png)
=![\frac{sin^{2}x }{sinx cosx} + \frac{cos^{2} x}{sinxcosx}](/tpl/images/1008/1447/347f8.png)
=![\frac{sinx}{cosx} + \frac{cosx}{sinx}](/tpl/images/1008/1447/fc1e2.png)
= tanx + cotx
tanx + cotx =![\frac{1}{sinxcosx}](/tpl/images/1008/1447/1daa6.png)
