    Answer:

    step by step calculation :

    To proof:

    tan²A – sin²A = tan² A sin²A

    from LHS,

    tan²A -sin²A

    = (sin²A / cos²A) – sin²A……[tan A=sin A/cos A]

    = (sin²A – sin²Acos²A) / cos²A

    = sin²A (1- cos²A) / cos² A [tan A = sinA / cos A]

    = tan²A sin²A= RHS

    .•. hence proved

    hope it helped:)
