Question

hello.math students
pls help.me with this question

we need to prove it


best answer gets brainliest ​

Answer 1

hence proved.........

Answer 2

Answer:

Step-by-step explanation:

tanA + cotA = (sinA/cosA) + (cosA/sinA)

= (sinA.sinA + cosA.cosA)/sinA.cosA

= 2 (sin²A + cos²A) / 2 sinA.cosA

= 2 × 1/sin2A

= 2 cosec2A

LHS=RHS

hence proved
