Question

prove that (sin○+cos○)(tan○+cot○)=sec○+cosec○​

Answer 1

Answer:

➡️here , (sino +coso)(tano+coto)=seco +coseco

Step-by-step explanation:

➡️solving LHS ,

➡️(sino+coso) (sino/coso + coso /sino )

hence,

➡️(sino+coso) ( sin²0 +cos²0). taking lcm and sin²o+cos²o=1

___________

sino coso

➡️ sino +coso

___________

sino coso

.➡️ sino coso

_______. +. _________. simply expanding it

sino coso sino coso

➡️. 1. +. 1

______. _________

coso sino

➡️. sec0 + coseco LHS=RHS
