Question

please prove 6)ii so many points

Answer 1

Hey !!!

Q 6 ..

cosec(¢ + @ ) = 1/sin(@+¢)

we know that .

sin(A + B ) = sinA×cosB + cosA×sinB

like that ..

1/sin(¢+@) = 1 /sin¢*cos@+ cos¢×sin@

dividing by sin¢×sin@ on numerator and denominator .

we get ..

1/sin¢×sin@
------------------------------------------------
sin¢×cos@ + cos¢×sin@ /sin¢*sin@

cosec¢•cosec@ /cot@+ cot¢

or, cosec¢ ×cosec@/cot¢ + cot@ Prooved here

RHS = LHS

Hope it helps you !!!
