Hey dosto! 👋



Class 10th trigonometry identity All important & PYQ Question Website Link - https://625e9b1685dad.site123.me/

I'm a recent 10th pass student (just like you!), making super easy & quick NCERT solutions. In this 2:58 min fast video, I prove Exercise 8.4 Question 5 (iii) from Chapter 8 – Introduction to Trigonometry (Class 10 NCERT Maths).
The identity: tan θ / (1 - cot θ) + cot θ / (1 - tan θ) = 1 + sec θ cosec θ
I solve it step-by-step by converting everything to sin & cos – very simple & beginner-friendly! Great for board exams, pre-boards, or last-minute revision.
