  • Prove that sin square theta + cos square theta =1 | class 10th | Trigonometric Identities
    Hello students welcome to my youtube channel Namokar coaching class k J sir. Students in this video we have proved the Trigonometric Identities.
    1- sin2A + cos2A =1
    2- 1 + tan2A = sec2A
    3- 1 + cot2A = cosec2A
    Students watch other videos of Chapter 8 by watching the playlists.
    Thanks for watching my video
