Question

prove that: 1+cosec A + cot A - 1/sin A = 1/sin A - 1/cosec A-cot A

Answer 1

Answer:

put the value of A = 45

Step-by-step explanation:

then

LHS

1 + Cosec 45 + Cot 45 - 1 / Sin 45

1 + √2 + 1 - √2

2

Now

RHS

1/Sin45 - 1/ cosec45 - cot 45

√2 - 1/√2 -1

1/√2 - 1

√2 - 2

LHS is not equal to RHA

so question is wrong
