Question

(1 +tan A + sec A) (1 + cot A - cosec A)​

Answer 1

Answer:

(1+tanA+secA) (1+cotA-cosecA)

1+cotA-cosecA+tanA+tanA.cotA-tanA.cosecA+secA+secA.cotA-secA.cosecA

1+cotA-cosecA+tanA+1/cotA.cotA-sinA/cosA.1/sinA+secA+1/cosA.cosA/sinA-1/cosecA.cosecA

1+cotA-cosecA+tanA+1-1/cosA+secA+1/sinA-1

1+cotA-cosecA+tanA-secA+secA +cosecA

1+cotA+tanA

1+cosA/sinA+sinA/cosA

(1+sinAcosA) /sinAcosA
