So LHS

(sinФ + cosecФ)/sinФ

=1 + 1/sin²Ф

= 1 + 1 + 1/sin²Ф - 1

= 2 + (1 - sin²Ф)/sin²Ф

= 2 + cos²Ф/sin²Ф {cosФ/sinФ=cotФ}

= 2 + cot²Ф

so LHS = RHS**proved**

(sinФ + cosecФ)/sinФ

=1 + 1/sin²Ф

= 1 + 1 + 1/sin²Ф - 1

= 2 + (1 - sin²Ф)/sin²Ф

= 2 + cos²Ф/sin²Ф {cosФ/sinФ=cotФ}

= 2 + cot²Ф

so LHS = RHS
