Hello student, Please find the answer to your question below
Cosec(A+B)
=1/ sin(A+B)
=1/(sin A cos B + cosA sinB)
=1/((cosecA)(secB)+(1/secA)(1/cosecB))
Now you can take LCM in the denomenator and solve it
Cosec(A+B)
=1/ sin(A+B)
=1/(sin A cos B + cosA sinB)
=1/((cosecA)(secB)+(1/secA)(1/cosecB))
Now you can take LCM in the denomenator and solve it
