*⃣ STEP-BY-STEP DISCUSSION *⃣
⏩ Firstly we write the question as it is on our sheet.
⏩ We convert tan theta into 1/cot theta
⏩ We calculated normally and proceeded.
⏩ We took "-" sign common to make the denominators equal, i.e., here, to make both denominators "1-cot theta".
⏩ We proceeded.
⏩ We use the formula which we had read in previous classes : a³-b³ = (a-b) (a²+ab+b²).
⏩ (1-cot theta) gets cancelled out from both numerator and denominator.
⏩ We proceeded normally step by step.
⏩ R. H. S. is thus obtained.
